Question

The lawn in front of Molly's house is 12mx 8m, whereas the lawn in front of Dolly's house is 15mx5m. A bamboo fencing is built around both the lawns. How much fencing is required for both?
​

Answer 1

Answer:

80 m

Step-by-step explanation:

The perimeter of the lawn in front of Molly’s house = 2(length + breadth) = 2(12 + 8) m = 2(20) m = 40 m

The perimeter of the lawn in front of Dolly’s house = 2(length + breadth) = 2(15 + 5) m = 2 × 20 m = 40 m

∴ Total length of fencing for both the lawns = (40 + 40) m = 80 m

Answer 2

Answer:

• The perimeter of the lawn in front of Molly’s house = 2(length + breadth) = 2(12 + 8) m = 2(20) m = 40 m The perimeter of the lawn in front of Dolly’s house = 2(length + breadth) = 2(15 + 5) m = 2 × 20 m = 40 m ∴ Total length of fencing for both the lawns = (40 + 40) m = 80 m
