Question

Find the area of a square park whose perimeter is 320 m
640 sq m
6400 sq m
1600 sq m
1280 sq m

Answer 1

Answer:

6400 sq m

Step-by-step explanation:

perimeter of square = 320

4 x side = 320

side = 320/4

side = 80 m

Now,

Area of square = side x side

= 80 x 80 = 6400 sq m

Answer 2

Step-by-step explanation:

Perimeter of a square = 4a

4a = 320 m

a = 320/4

a= 80

Now, Area of square = a²

a = 80

a² = 80 × 80

6400 = Area of square

6400 sq m
