Final answer:
Using the formula for the area of a rectangle (Length x Width = Area), we can determine the width of the yard by dividing the given area (720 sq ft) by the given length (30 ft). This results in a width of 24 feet.
Step-by-step explanation:
To determine the width of the front yard, we can use the formula for the area of a rectangle which is length multiplied by width (L x W = Area). Given that the length is 30 feet and the area is 720 square feet, we can set up the equation 30 x W = 720 and solve for W (width).
Dividing both sides of the equation by 30, we find that W = 720 / 30 which equals 24 feet. Therefore, the width of Mr. Fitch's front yard is 24 feet.
