perimeter = 12m
let
breadth = x and length = 2x+3
then,
perimeter = 2(l+b)
2(2x+3+ x) = 12
4x+6+2x = 12
6x+6 = 12
6x = 12-6
x=6/6
x= 1
So,
length = 2x+3 = 5
width = x = 1
let
breadth = x and length = 2x+3
then,
perimeter = 2(l+b)
2(2x+3+ x) = 12
4x+6+2x = 12
6x+6 = 12
6x = 12-6
x=6/6
x= 1
So,
length = 2x+3 = 5
width = x = 1
