SSAT Elementary Level Quantitative - How to find the area of a square

Use the following square to solve the problem:

Square1

Find the area.

$25\text{cm}^2$

$20\text{cm}^2$

$15\text{cm}^2$

$10\text{cm}^2$

$\text{There is not enough information to solve the problem.}$

Explanation

To find the area of a square, we will use the following formula:

$A = l \cdot w$

where l is the length and w is the width of the square.

Now, given the square

Square1

we can see the length is 5cm. Because it is a square, all sides are equal. Therefore, the width is also 5cm. So, we can substitute

$A = 5\text{cm} \cdot 5\text{cm}$

$A = 25\text{cm}^2$

Find the area of a square with side length 3.

Explanation

A square has sides that are all equal. Area is length times width, and in the case of a square it is the side measurement times itself. $5\times5=25$

Find the area of a square whose side length is 0.1.

Explanation

To solve, simply use the formula for the area of a square below.

Thus,

What is the area of a square that has a side measuring 3 inches in length?

Explanation

A square has four equal sides. The area of a square is found by the equation $Area=side\times side$ .

$3:in :\times:3:in=9:in^2$

Find the area of a square with a side of .

Explanation

Write the formula for area of a square.

Substitute the side length.

What is the area of the square?

Explanation

The area of a square is equal to the length of one side multiplied by itself.

$5\times 5 = 25$

A square has a perimeter of units. What is the area of the square?

units squared

Explanation

Since a square has four sides of the same length, you can divide its perimeter by to figure out the length of one of its sides: units. The area of a square can be calculated by multiplying two of its sides together, so the area of this square is units squared, because .
