Answer:

The answer to your question is the second choice

Step-by-step explanation:

Data

Large rectangle                        Small rectangle

base = 15 ft                                 base = 11 ft

height = 13 ft                               height = 9 ft

Process

1.- Express the area of the large rectangle

Area = base x height

Substitution

Area = (15)(13)

2.- Express the area of the small rectangle

Area = (11)(9)

3.- Write the area of the shaded region

Shaded area = Area of the large rectangle - Area of the small rectangle

-Substitution

Shaded area = (15)(13) - (11)(9)

Formula for the area of a rectangle:

A = lw         (A = area       l = length     w = width)

To find the area of the shaded region, you first need to find the area of the smaller rectangle and the area of the larger rectangle.

Larger rectangle:     A = 15(13)

Smaller rectangle:     A = 11(9)

Now that you know the areas, you can subtract the area of the larger rectangle by the area of the smaller rectangle to find the area of the shaded region:       [because the smaller rectangle is the unshaded region]

[Total Area - Area of Unshaded Region = Area of Shaded Region]

Larger Rectangle's Area - Smaller Rectangle's Area = Area of Shaded Region

15(13) - 11(9) = A      Your answer is the 2nd option
