Question

A square-shaped park has an area of 400 yd2. what are the dimensions of the park

Answer 1

If it’s a perfect square the measurements of length and width would be 20yrdx20yrd

20x20=400

Answer 2

20 yd X 20 yd

Explanation:

Hello

I think i can help you with this

The area of ​​a square is equal to the product side by side.

(1)
`A=l*l\\A=l^(2)`

Step 1

Let

`A=400\ yd^(2)\\`

replacing A in (1)

`A=400\ yd^(2)\\400\ yd^(2)=l^(2)`

isolating l

`400\ yd^(2)=l^(2) \\l =\sqrt{400\ yd^(2)}\\l= 20 yd`

only the positive root because it is a distance.

hence, the dimensions of the park are 20 yd X 20 yd

Have a great day
