Erika is painting a rectangular painting. The painting has a length of 12 and a width of 10 inches. Use the Distributive Propert
antiseptic1488 [7]

Given:

Length of the painting = 12 inches

Width of the painting = 10 inches

To find:

The area of the rectangular painting by using Distributive Property to decompose the factor 12.

Solution:

The area of a rectangle is

A=length\times width

So, the area of the rectangular paining is

A=12\times 10

Using Distributive Property to decompose the factor 12, we get

A=(10+2)\times 10

A=(10\times 10)+(2\times 10)

A=100+20

A=120

Therefore, the area of the rectangular painting is 120 square inches.
