Question

lashonda wants to plant grass in her backyard. her backyard is in the shape of a rectangle. its length is 32 feet and its width is 21 feet. suppose each pack of seed covers 12 square feet. how many packs of seed will she need to cover the backyard?

Explanation:

Step1: Calculate the area of the backyard

The area \(A\) of a rectangle is given by \(A = \text{length}\times\text{width}\). Here, length \(l = 32\) feet and width \(w = 21\) feet. So, \(A=32\times21 = 672\) square feet.

Step2: Determine the number of seed packs

If each pack covers \(12\) square feet, then the number of packs \(n=\frac{\text{Area of backyard}}{\text{Area covered by one pack}}\). So, \(n=\frac{672}{12}=56\).

Answer:

56
