Question

The Length and breadth of a Rectangle is in Ratio 4 Ratio 3 If its perimeter is 84 .Find its Length and breadth

Answer 1

Answer:

I hope it will help you

Step-by-step explanation:

solution,

let the Length and breadth of a Rectangle be l and b respectively. Such that

l:b = 4:3

or, l/b = 4/3

or, l = 4b/3

we know

perimeter = 2(l+b)

or, 84 = 2(4b/3 + b)

or, 84 = 14b/3

or, b = 84 x 3/17

so, b = 18

Also,

l = 4b/3

or, l = 4 x 18 / 3

so, l = 24

therefore

l = 24 and b = 18
