56 pack

Step-by-step explanation:

To find the number of packs of seed needed, we will first find the area of the rectangular backyard. We're given that the length is 32 feet and the width is 21 feet.

We get the following. Area = length * width = * 3221 = 672 square feet So the area of the backyard is 672 square feet. Each pack of seed covers 12 square feet. So we can find the number of packs of seed needed as follows. = : 6721256 packs Thus, Justin will need 56 packs of seed.
