Worked Solution
Step 1: Identify the base and height of the triangle.
Base = length of rectangle = 30 m
Height = half the width of rectangle = ½ × 20 = 10 m
Step 2: Apply the area formula for a triangle.
Area = ½ × base × height
Area = ½ × 30 × 10
Step 3: Calculate.
½ × 30 = 15
15 × 10 = 150 m²
Answer: The area of the triangular community garden is 150 m².
Answer: 150 m²
Correct answer: 150 m²
