Question

the ratio of lenght to breadth of a rectangle is 7:4.If the perimeter of the rectangle is 220 m.find the lenght of the rectangle?​

Answer 1

Step-by-step explanation:

let's take the length and breadth as 7x and 4x

2×(l+b) = 220 m

2×( 7x +4x)=220

2×11x=220

22x= 220

x= 220/22

x= 10

therefore length = 7x = 7×10 = 70m

breadth =4x =4×10= 40 m
