Hint:

### Given , the boundary of square garden .Find the length of side of square garden and then Find the area of square by using general formula.

## The correct answer is: The area of the square garden is 400 sq. m

### ANS :- 400 sq. m should be the area of the square garden.

Explanation :-

Step 1:- Find the length of side of square garden

Let the side length of the square garden be a then the perimeter of that square is 4a .

Given , perimeter (or) boundary = 80 m

∴ a = 20 m

Step 2:- Find the area of square by using general formula

Area of square with side length a is .

We get a = 20 m the area of square garden =

∴The area of the square garden is 400 sq. m.
