Question

Michelle purchased a kids table with a square top if the area of the square top is 400 square inches what is the length of one of the sides

Answer 1

400 in² = (20 in)²

The area of a square is the square of the side length.

The length of one of the sides is 20 inches.

Answer 2

Answer: 20 inches

Step-by-step explanation:

We know that the area of a square is given by :-

$\text{Area}=(\text{Side})^2$

Given : Michelle purchased a kids table with a square top if the area of the square top is 400 square inches .

Let s be the side of the square , then we have the following equation:-

$s^2=400$

Taking square root on both the sides , we get

$s=\sqrt{400}=\sqrt{20\times20}=20$

Hence, the  length of one of the sides =  20 inches
