Problema Solution
A garden is shaped like a rectangle whose perimeter is 60ft. The length is 4ft more than the width. Find the length and the width.
Answer provided by our tutors
Let
l = the length
w = the width
P = 60 ft is the perimeter
Since P = 2l + 2w we have:
2l + 2w = 60 divide both sides by 2
l + w = 30
The length is 4 ft longer than the width:
l = w + 4
We have the following system of equations:
l + w = 30
l = w + 4

........
l = 17 ft
w = 13 ft
the length is 17 ft while the width is 13 feet.
