Question

kaitlin 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?
packs

Explanation:

Step1: Calculate area of rectangle

The area \( A \) of a rectangle is given by the formula \( A = \text{length} \times \text{width} \). Here, length \( = 31 \) feet and width \( = 24 \) feet. So, \( A = 31 \times 24 \). Calculating that, \( 31\times24 = 744 \) square feet.

Step2: Find number of seed packs

Each pack covers 12 square feet. To find the number of packs, divide the total area by the area per pack. Let \( n \) be the number of packs. Then \( n=\frac{744}{12} \). Calculating this, \( \frac{744}{12}=62 \).

Answer:

62
