#### Answer

(x + 5)(x + 3) = x(x + 3) + 5(x + 3). This is the distributive property.

#### Work Step by Step

The first way to find the area is to multiply the entire length with the entire width:
(x + 5)(x + 3)
The second way is to add the small thing rectangle (width x) with the thick rectangle (width 5):
x(x + 3) + 5(x + 3)
(x + 5)(x + 3) = x(x + 3) + 5(x + 3). This is the distributive property.
