Worked Solution

Step 1: Find the area of the full rectangle. Area of rectangle = length × breadth = 10 × 6 = 60 m² Step 2: Find the area of the triangular corner cut away. Area of triangle = ½ × base × height = ½ × 4 × 6 = 2 × 6 = 12 m² Step 3: Subtract the triangle from the rectangle to get the remaining garden area. Remaining area = 60 − 12 = 48 m² Answer: 48 m²

Correct answer: 48 m²
