Question

ratio of 2 sides of llgm is 4:3 if its perimeters is 56 find length of its sides

Answer 1

let the total ratio be x
then the sides will be 4x and 3x respectively
as we know that
perimeter =sum of all sides
56=4x+4x3x+3x
56=14x
x=4

Answer 2

let the ratio be 4x and 5x
:. perimeter=56
as know perimeter= l*b
56 =(4x*5x)
56= 20x
we can change their sides
20x =56
x=56/20
=>2.8
