let length = 3x & breadth = 2x
A = l x b
726 = 3x X 2x
726 = 6x^2
x^2 = 726 / 6
x^2 = 121
x = 11 so, l = 33m, & b = 22m
P = 2(l + b)
= 2 ( 33 + 22 )
= 2 x 55
= 110 m
A = l x b
726 = 3x X 2x
726 = 6x^2
x^2 = 726 / 6
x^2 = 121
x = 11 so, l = 33m, & b = 22m
P = 2(l + b)
= 2 ( 33 + 22 )
= 2 x 55
= 110 m
