Question

mary wants to plant grass in her backyard. her backyard is in the shape of a rectangle. its length is 28 feet and its width is 25 feet. suppose each pack of seed covers 14 square feet. how many packs of seed will she need to cover the backyard?

Explanation:

Step1: Calculate area of rectangle

The formula for the area of a rectangle is \( A = l \times w \), where \( l \) is length and \( w \) is width. Here, \( l = 28 \) ft and \( w = 25 \) ft. So, \( A = 28 \times 25 = 700 \) square feet.

Step2: Find number of seed packs

Each pack covers 14 square feet. To find the number of packs, divide total area by area per pack: \( \frac{700}{14} = 50 \).

Answer:

50
