Question

Area of a rectangle is 432m square. If the length and breadth are in the ratio of 4:3, find its perimeter ​

Answer 1

let the length and breadth of the rectangle be 4x, 3x

therefore,

l x b = area

therefore,

4x x 3x=432m²

12x²=432

x²=432/12=36

x=6

length =24 and breadth=18

perimeter=2(24+18)=2(42)=84m
