Answer 2

Answer:

(a) 1 ft

(b) 9 yd

Step-by-step explanation:

(a)

Given perimeter = 4 ft.

We know that perimeter of a square = 4 * length of a side.

⇒ 4 = 4* length of each side

⇒ (4/4) = length of each side.

⇒ Length of each side = 1 ft.

----------------------------------------------------------------------------------------------------

(b)

Given, Area of square = 81 yd²

We know that Area of square = (s)²

⇒ 81 = (s)²

⇒ √81 = s

⇒ s = 9 yd.

Therefore, length of each side = 9 yd.

Hope it helps!
