The sides of a rectangle are in the ratio 4:3 and its area is 972sq.m find the perimeter of rectangle  Choices.
A) 120m	B) 122m	C) 124m	D) 126m	E) 128m
Explanation:   let 4x and 3x be sides of the rectangle   We know that area of rectangle = l×b   4x × 3x = 972   12x2 = 972   X2 = 81   X = 9   Therefore length = 4x = 4×9 = 36m   Breadth = 3x = 3×9 = 27m   Therefore perimeter = 2 (l+b) = 2(36+27) = 126m   Answer: Option 126m
