Answer 1

Answer: It will cost him $237 to seed the entire backyard

Explanation:

Hi, to answer this question, first, we have to calculate the area of the rectangular backyard:

Area of a rectangle = length x width

Replacing with the values given:

A = 20 x 15 = 300 ft2

Since seed cost 0.79 per square foot, we simply have to multiply that price by the area:

0.79 x 300 = $237

It will cost him $237 to seed the entire backyard
