# The total area of the rectangle is 10 ft^2 What is the width and length of the rectangle, given that the width is 3 feet less than the length?

$10 = x \times \left(x - 3\right)$

#### Explanation:

x is 5 feet because the length is 5 ft and the width is 2 ft.

$10 = 5 \times \left(5 - 3\right)$

$10 = 5 \times 2$

I found it by trial and error. You can try quadratic formula to solve the problem.
