Trey wants to plant grass in his backyard. his 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 he need to cover the backyard?

The first step to solve this problem is to compute for the area of the rectangular backyard. The formula in computing the area of a rectangle is:

A = LW

Substituting the given measurement to the formula:

A = 31 (24)

A = 744 square feet

The area of the backyard is 744 square feet.

Since each pack of seed covers 12 square feet, you need to divide this to the total area of the backyard.

Therefore, you need 62 (744 / 12) packs of seed to cover the backyard.
