Problema Solution
The width of a rectangle is 15 cm less than its length. The perimeter is 98 cm. Find the dimensions of the rectangle.
Answer provided by our tutors
let
w = the width of the rectangle
l = the length of the rectangle
the width of a rectangle is 15 cm less than its length
w = l - 15
the perimeter is 98 cm
w + l = 98
by solving the system of equations
w = l - 15
w + l = 98
we find
w = 41.5 cm
l = 56.5 cm
