Charles backyard is in the shape of a rectangle and the length of his backyard is 19.5 ft it cost her 945dollars to fence in the yard and it cost $15 per foot what is the width of Charles backyard

Step-by-step explanation:

The backyard is rectangular in shape.

The formula for determining the area of a rectangle is expressed as

Area = length * width

If the length of his backyard is 19.5 ft, then the area of the backyard would be 19.5W square feet.

it cost her 945 dollars to fence the yard. If it cost $15 per foot, it means that the total area that was fenced is

945/15 = 63 square feet.

Since the area of the backyard is 19.5W square feet, then

19.5W = 63

W = 63/19.5

W = 3.2 feet
