A 36 inch board would be multiplying 1 1/2 by 2 so it would be 3 foot.
A 72 inch board would be multiplying 3 foot by 2 so it would be 6 ft
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
So, the area of the rectangular paining is
Using Distributive Property to decompose the factor 12, we get
Therefore, the area of the rectangular painting is 120 square inches.
