Problema Solution
the length of a rectangle is 5 more than 3 times its width. the perimeter is 170 feet. find the dimensions of the rectangle.
Answer provided by our tutors
let
l = the length of the triangle, l>0
w = the width of the triangle, w>0
the length of a rectangle is 5 more than 3 times its width.
l = 5 + 3w
the perimeter is 170 feet.
2(l + w) = 170
by solving the system of equations:
l = 5 + 3w
2(l + w) = 170
we find:
l = 65 ft
w = 20 ft

the dimensions of the rectangle are: the length is 65 feet and the width is 20 feet.
