Answer:
The side of the square is 20 meters and area is 400 sq, meters
Explanation:
The perimeter of a square with side length a is given by, P = 4a.
Now, given that 4a = 80
⇒ a = 20 meters.
Therefore, the area of the square is, A = a² = 20² = 400 square meters.
Hence, the side of the square is 20 meters and the area is 400 sq, meters. ( Answer )
