Problema Solution
The perimeter of a rectangular lot is 980 m. The length of the field is 30 m less than three times the width. Find the dimensions.
Answer provided by our tutors
let width = x , length = 3x-30
perimeter = 980
2(x+3x-30) = 980
4x -30 = 490
4x = 520
x = 130
width = 130m ,length = 3*130-30 = 360m
