Question

Megan is placing fifteen 1-foot by 1-foot stepping stones in her garden. The garden is 10 feet wide and 15 feet long. What is the area of her garden that is not covered by stepping stones?

a. 85 ft2
b. 135 ft2
c. 150 ft2
d. 165 ft2

Answer 1

The total area of the garden is calculated by the multiplying the length and the width of the garden. In this case, it is equal to 10x15 = 150 ft^2. However, we have to determine the area that is not covered by the stones. The total area of the stepping stones would be 15x1x1= 15 ft^2

Area not covered = 150 - 15= 135 ft^2
