Question
A rectangular garden is 20 m long and 15 m wide. If a
path of width 2 m is built around the garden, what is the area of the path?Solution
Area of the garden = length * width = 20 * 15 = 300 m². Dimensions of the garden including the path = (20 + 2*2) * (15 + 2*2) = 24 * 19 = 456 m². Area of the path = Total area - Area of the garden = 456 - 300 = 156 m². Correct option: a) 156 m²
[192 ÷ 6 × 5] ÷ (? + 3) = 20Â
