Question

The area of square is 4 times it's perimeter,find the length of square.​

Answer 1

Answer:

let the side of the square is x cm

then it's perimeter is 4x cm

so,it's area is 4.4x sq cm=16x sq cm

again the area of a square of side x cm is

x^2 sq cm

so,

x^2=16 x

=> x= 16

so,the length of the square is 16 cm
