Question

A rectangular lawn is 60 feet wide and 90 feet long.

a. What is the area of the lawn?

b. A bag of fertilizer covers 50 square feet. How many bags of fertilizer do you need to cover the entire lawn? Explain.

Answer 1

Explanation:

area for a rectangle would be A=bl

Or area is base (width) times length, so plug in the numbers

60 x 90

5400 ft2
now to figure out the number of bags you would divide the area of the lawn by the area the fertilizer covers

5400/50

You get 108

You would need 108 bags to cover the lawn.

Answer 2

a. 5,400 ft. b. 108 bags

Explanation:

a. 60 x 90 = 5,400 ft.

b. 5,400 / 50 = 108 bags
