Question

find the area of asquare whose perimeter is 320​

Answer 1

Answer:

Area is 6400 cm²

Step-by-step explanation:

perimeter = 4 x side

4 x side = 320

side = 320/4

side = 80cm

Area = side x side

        = 80 x 80

        = 6400 cm²

Answer 2

Answer:

6400m2

Step-by-step explanation:

Perimeter of a square = 320m

P = S × 4   so S = P/4

So side = P/4

= 320/4 = 80m.

So now that we have the side of the square , we can find the area of the square

A = S × S

= 80 × 80 = 6400m2

So area of the square is 6400m2
