### Example Question #103 : Geometry

The width of a rectangle is half of its length. If the width is given as what is the perimeter of the rectangle in terms of ?

**Possible Answers:**

**Correct answer:**

The sum of the widths is and since the width is half the length, each length is *. *Since there are 2 lengths we get a total perimeter of *.*

### Example Question #104 : Geometry

The above figure shows the size and shape of a yard that is to be surrounded by some fence. How many feet of fence will be needed?

Note: all sides meet at right angles.

**Possible Answers:**

**Correct answer:**

The best way to see that 750 feet of fence are needed is to look at this augmented diagram.

Note that two of the sides are extended to form a smaller rectangle whose sides can be deduced by subtraction. Since opposite sides of a rectangle are congruent, this allows us to fill in the two missing sidelengths of the original figure.

Now add:

### Example Question #1 : How To Find The Perimeter Of A Rectangle

Give the perimeter of the rectangle in the above diagram.

**Possible Answers:**

**Correct answer:**

The perimeter of a rectangle is the sum of the length and the width, multiplied by 2:

The rectangle has a perimeter of 38 centimeters.

### Example Question #111 : Geometry

Give the perimeter of the rectangle in the above diagram.

**Possible Answers:**

**Correct answer:**

The perimeter of a rectangle can be calculated by multiplying two by the sum of the length and width of the rectangle.

The perimeter of the rectangle is inches.

### Example Question #112 : Geometry

Figure NOT drawn to scale.

Give the perimeter of the green polygon in the above figure.

**Possible Answers:**

The perimeter cannot be determined from the information given.

**Correct answer:**

Since opposite sides of a rectangle have the same measure, the missing sidelengths can be calculated as in the diagram below:

The sidelengths of the green polygon can now be added to find the perimeter:

### Example Question #113 : Geometry

The width of a rectangle is one-third of its length. If the width is given as what is the perimeter of the rectangle in terms of ?

**Possible Answers:**

**Correct answer:**

The perimeter of a rectangle is the sum of its sides.

The sum of the widths is and since the width is one-third of the length, each length is . Since there are lengths we get a total of . Widths + lengths =

### Example Question #51 : Rectangles

You are given equilateral triangle and Rectangle

with .

What is the perimeter of Rectangle ?

**Possible Answers:**

**Correct answer:**

is equilateral, so .

Also, since opposite sides of a rectangle are congruent,

and

The perimeter of Rectangle is

### Example Question #1 : How To Find The Perimeter Of A Rectangle

A hectare is a unit of area equal to 10,000 square meters.

A 150-hectare plot of land is rectangular and is 1.2 kilometers in width. Give the perimeter of this land.

**Possible Answers:**

**Correct answer:**

150 hectares is equal to square meters.

The width of this land is 1.2 kilometers, or meters. Divide the area by the width to get:

meters

The perimeter of the land is

meters, or kilometers.

### Example Question #3 : How To Find The Perimeter Of The Rectangle
