Explanation:

Given:

Alex is planning on making a square shape playground in the back yard.

He wants me to only use 400 square inches

Area of Square Play ground = 400 square inches

To Find:

Dimension of his playground = ?

Solution:

Let the square ground dimension be "x"

We know area of Square is given as

`\textrm{Area of Square (play ground) }=side* side=(side)^(2)`

Substituting the values we get

`400=(x)^(2)`

Square Rooting we get

`x=√(400)=20\ inches`

Therefore,

Dimension of Alex playground is

20 inch × 20 inch
