Answer: 15
Explanation:
Length of garden = 45 feet
Width of garden = 15 feet
One truckload covers 45 square feet
How may truck load will cover the entire garden.
Area of rectangle = Length × width
Area of rectangular garden = 45 × 15
Area of rectangular garden = 675 square feet
1 truckload of mulch = 45 square feet
y = 675 square feet
45y = 675
y = 675 ÷ 45
y = 15 truck loads of mulch
15 truckloads of mulch will cover the entire garden
