Question

A square has an area of 49 square inches. how long are its sides

Answer 1

Explanation:

We know that,

Area of a square = l^2

so in this case, we form an equation:

l^2=49 square inches

Now taking square root on both sides

`√(l)`^2=
`√(49)`

l=7 inches

so each side is 7 inches

Hope that helps

Answer 2

7 in

Explanation:

A square has an area of 49 square inches. how long are its sides

A = l²

inverse formula

l = √A

l = √49

l = 7 in
