Question

length and breadth of a rectangle plot are in the ratio 5 : 3 if the length is 45 M the perimeter will be

Answer 1

let length be = 5x
breadth = 3x
then
5x=45
x=9
breadth=21
perimetre = 2(l+b)
                = 2(45+21)
                = 2x 66 = 132m

Answer 2

length and breadth are in the ratio 5:3
let it be 5x and 3x
length is 45
5x=45
x=45/5
x=9m
so breadth is 3x=3*9
                          =21m
perimeter is 2(l+b)
2(45+21)
2(66)
132
132m is the perimeter
