perimeterof rectangle =perimeter of square
area of square = a²
36²=a×a×
=6×6
a = 6
perimeter of square=4a
=4×6
24cm
∴ perimeter of retangle =24cm
perimeter of rectangle =2(l+b)
24cm=2(2x +x)
24=4x+2x
24=6x
6x=24
x=24÷6
x=4
∴length of the rectangle=2x=2×4=8
breath of rectangle =x=4
hope you understood
