Problema Solution
The length of a rectangular garden is 10 feet longer than its width. The garden's perimeter is 212 feet. Find the length of the garden.
Answer provided by our tutors
let
l = the length of the rectangle
w = the width of the rectangle
the length of a rectangular garden is 10 feet longer than its width
l = 10 + w
perimeter is 212 feet
2(l + w) = 212 divide both sides by 2
l + w = 106
w = 106 - l
plug w = 106 - l into l = 10 + w
l = 10 + 106 - l
by solving we find
l = 58 ft
