Question

A large blue blanket measures 12 ft. by 8 ft. A small blue blanket measures 5 ft. by 3 ft. What is the difference in the areas of the two blankets?

a) 29 sq. ft.

b) 47 sq. ft.

c) 63 sq. ft.

d) 77 sq. ft.

Answer 1

The difference in the areas of the two blankets is calculated by subtracting the area of the small blanket (15 sq. ft.) from the area of the large blanket (96 sq. ft.), resulting in a difference of 81 sq. ft.

This correct answer is none of the above.

Step-by-step explanation:

The difference in the areas of the two blankets can be calculated by finding the area of each blanket and then subtracting the smaller area from the larger area.

The area of a rectangle is found by multiplying its length by its width. So, for the large blue blanket that measures 12 ft. by 8 ft., the area is 12 ft × 8 ft = 96 sq. ft.

For the small blue blanket that measures 5 ft. by 3 ft., the area is 5 ft × 3 ft = 15 sq. ft. To find the difference, we subtract the area of the small blanket from the area of the large blanket: 96 sq. ft − 15 sq. ft = 81 sq. ft.

This correct answer is none of the above.
