Problema Solution

perimeter is 210 ft. squared. the length is 3 ft less than 3 times the width

Answer provided by our tutors

let


l = the length

w = the width

P = 210 ft the perimeter of the rectangle


the length is 3 ft less than 3 times the width


l = 3w - 3


the formula for the perimeter is P = 2(l + w)


2(l + w) = 210


by solving the system of equations


l = 3w - 3

2(l + w) = 210


we find


l = 78 ft


w = 27 ft
