### Example Question #41 : How To Find The Perimeter Of A Rectangle

Find the perimeter of a rectangle with a length of 8cm and a width of 6cm.

**Possible Answers:**

**Correct answer:**

To find the perimeter of a rectangle, we will use the following formula:

where *a, b, c, *and *d* are the lengths of the sides of the rectangle.

Now, we know the length of the rectangle is 8cm. Because it is a rectangle, we know the opposite side is also 8cm.

We know the width of the rectangle is 6cm. Because it is a rectangle, we know the opposite side is also 6cm.

Knowing this, we can substitute into the formula. We get

### Example Question #42 : How To Find The Perimeter Of A Rectangle

Use the following rectangle to answer the question:

Find the perimeter.

**Possible Answers:**

**Correct answer:**

To find the perimeter of a rectangle, we will use the following formula:

where *a, b, c, *and *d* are the lengths of the sides of the rectangle.

Now, given the rectangle

we can see the length is 11in. Because it is a rectangle, the opposite side is also 11in. We see the width is 5in. Because it is a rectangle, the opposite side is also 5in.

Knowing this, we can substitute into the formula. We get

### Example Question #43 : How To Find The Perimeter Of A Rectangle

Find the perimeter of a rectangle with a length of 9in and a width of 4in

**Possible Answers:**

**Correct answer:**

To find the perimeter of a rectangle, we will use the following formula:

where *a, b, c, *and *d* are the lengths of the sides of the rectangle.

So, we know the length of the rectangle is 9in. Because it is a rectangle, the opposite side is also 9in. We know the width of the rectangle is 4in. Because it is a rectangle, we know the opposite side is also 4in.

Knowing this, we can substitute into the formula. We get

### Example Question #101 : Rectangles

Use the following rectangle to answer the question:

Find the perimeter.

**Possible Answers:**

**Correct answer:**

To find the perimeter of a rectangle, we will use the following formula:

where *a, b, c, *and *d* are the lengths of the sides of the rectangle.

Now, let's look at the rectangle.

We can see the length is 11 inches. Because it is a rectangle, the opposite side is also 11 inches. We can see the width is 5 inches. Because it is a rectangle, the opposite side is also 5 inches.

Knowing this, we can substitute into the formula. We get

### Example Question #45 : How To Find The Perimeter Of A Rectangle

Find the perimeter of a rectangle with a width of 5cm and a length that is two times the width.

**Possible Answers:**

**Correct answer:**

To find the perimeter of a rectangle, we will use the following formula:

where *a, b, c* and *d* are the lengths of the sides of the rectangle.

Now, we know the width of the rectangle is 5cm. Because it is a rectangle, the opposite side is also 5cm. We also know the length is two times the width. Therefore, the length is 10cm. Because it is a rectangle, the opposite side is also 10cm.

Knowing this, we can substitute into the formula. We get

### Example Question #46 : How To Find The Perimeter Of A Rectangle

Use the following rectangle to answer the question.

Find the perimeter.

**Possible Answers:**

**Correct answer:**

To find the perimeter of a rectangle, we will use the following formula:

where *a, b, c, *and *d* are the lengths of the sides of the rectangle.

Now, given the rectangle

We can see the length is 9cm. Because it is a rectangle, the opposite side is also 9cm.

We can see the width is 7cm. Because it is a rectangle, the opposite side is also 7cm.

Knowing this, we can substitute into the formula. We get

### Example Question #47 : How To Find The Perimeter Of A Rectangle

Use the following rectangle to answer the question:

Find the perimeter.

**Possible Answers:**

**Correct answer:**

To find the perimeter of a rectangle, we will use the following equation:

where *a, b, c, *and *d* are the lengths of the sides of the rectangle.

Now, given the rectangle

we can see the length is 11in. Because it is a rectangle, the opposite side is also 11in.

We can see the width of the rectangle is 5in. Because it is a rectangle, the opposite side is also 5in.

Knowing this, we can substitute into the formula. We get

### Example Question #48 : How To Find The Perimeter Of A Rectangle

A rectangle measures inches along its short side, and inches along its long side. What is the perimeter of the rectangle?

**Possible Answers:**

**Correct answer:**

To find the perimeter of any object, simply add the length of each side together. In the case of the rectangle, there are two short sides, and two long sides, so you can also multiply the short side by two, the long side by two, and add the sums. The best answer is:

inches
