Jamal's Lawn Service will charge $28 for fertilizing this lawn.
Step-by-step explanation:
- Step 1: Find the area of the lawn. It is in U shape which is a rectangle from which a square has been cut off. So the area of the lawn can be found by subtracting the area of the square from the area of the rectangle.
Area of the rectangle = length × width; here length = 4 yd and width = 3 yd
⇒ Area = 4 × 3 = 12 yd²
Area of the square = (side length)²; Here side length = 2 yd
⇒ Area = 2² = 4 yd²
∴ Area of the lawn = 12 - 4 = 8 yd²
- Step 2: Find the cost of fertilizing the lawn.
Cost of fertilizing 1 sq. yd = $3.50
∴ Cost of fertilizing 8 sq. yards = 8 × 3.50 = $28
