Problema Solution
The width of a rectangular lawn is 15 meters less than the length. Find the dimensions of the lawn if the perimeter is 86 meters.
Answer provided by our tutors
let
w = the width
l = the length
P = 86 m the perimeter
The width of a rectangular lawn is 15 meters less than the length:
w = l - 15
the perimeter is 86 meters:
2(l + w) = 86 divide both sides by 2
l + w = 43
by solving the system of equations:
w = l - 15
l + w = 43
we find:
l = 29 in
w = 14 in

the dimensions of the rectangle are: the length is 29 in and the width is 14 in.
