Question

The length of the rectangle is 6 m less than three times its breath. It its perimeter is 148 m, find the dimensions of the rectangle

Answer 1

let breadth be: x
length would be: 3x-6

perimeter: 2(l+b)

2(x+3x-6) = 148
4x-6 = 74
4x = 80
x = 20m

hence breath is 20m
so, length would be 3(20)-6 = 54m
