Question

Maria wants to plant grass in her backyard. Her backyard is in the shape of a rectangle. Its length is

31

feet and its width is
24

feet. Suppose each pack of seed covers
12

square feet. How many packs of seed will she need to cover the backyard?

Answer 1

62 packs of seeds

Step-by-step example

So this is an area problem. The shape we are trying to find the area of is a rectangle. Since we are finding the area of a rectangle you use the formula L×W (Length×Width).

Both of these are given so you want to multiply the length (31) by its width (24) (31×24). After multiplying you should get 744 square feet. Since Maria wants to plant grass in her rectangular shape backyard and each pack only covers 12 square feet, you are going to do 744 divided by 12 (744÷12).

After dividing you will get 62 so your answer will be 62 packs of seeds.
