Problema Solution
The length of a rectangle is 7 ft longer than twice the width. If the perimeter is 98 ft, find the length and width of the rectangle.
Answer provided by our tutors
let
l = the length of the rectangle
w = the width of the rectangle
the length of a rectangle is 7 ft longer than twice the width:
l = 7 + 2w
the perimeter is 98 ft:
2(l + w) = 98 divide both sides by 2
l + w = 49
by solving the system of equations:
l = 7 + 2w
l + w = 49
we find:
l = 35 ft
w = 14 ft
