Answer 2

Answer:

= Area = 10000 meter

Step-by-step explanation:

The Perimeter of a square is 400 meter

So,

The side will be = Perimeter = 4 x side

let side will be x

= 400 = 4x

= 4x = 400

= x = 400/4

= x = 100

Side will be 100 meter

Area = side x side

= Area = 100 x 100

= Area = 10000 meter
