Question

The measure of two adjacent sides of rectangle are in the ratio 3:4. if the perimeter of the rectangle is 686 cm, find its lenght and breadth​

Answer 1

Step-by-step explanation:

let the sides be 3x and 4x

perimeter=2(l+b)

686=2(3x+4x)

686÷2=7x

343÷7=x

49=x

hence,

x = 49

length = 4x = 4x49 = 196

breadth = 3x = 3×49 = 147
