Answer:
20 yd X 20 yd
Step-by-step explanation:
Hello
I think i can help you with this
The area of a square is equal to the product side by side.
(1)[tex]A=l*l\\A=l^{2}[/tex]
Step 1
Let
[tex]A=400\ yd^{2}\\[/tex]
replacing A in (1)
[tex]A=400\ yd^{2}\\400\ yd^{2}=l^{2}[/tex]
isolating l
[tex]400\ yd^{2}=l^{2} \\l =\sqrt{400\ yd^{2}}\\l= 20 yd[/tex]
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
