A rectangular garden is 20 ft longer than it is wide. Its area is 1125 ft^2. What are its dimensions?

Its width equals__________ feet and its length equals _______ feet.

A rectangle with aside 'L' and other side 'W', will have an area A = ?

Draw a rectangle with sides 'L' and 'W'.

What information does the problem about 'L' and 'W("garden is 20 ft longer than it is wide")?

We can say that the width is W.
The length then would be W+20

Here, we have 2W and 2(W+20)s in the rectangle

Area:
W * (W + 20) = 1125


Factor:
W^2+ 20W = 1125
W^2+20W-1125=0

The quadratic roots:
-45
25

Width cannot be negative, so width = 25ft, length = 45ft

CHECK:
25*45 = 1125
We are done!
