The lawn in front of Molly’s house is 12m × 8m, whereas the lawn in front of Dolly’s house is 15m × 5m. A bamboo fencing is built around both the lawns. How much fencing is required for both?
For Molly’s House.
Length, l = 12 m
Breadth, b = 8 m
Perimeter of the lawn = Fencing required = 2 × (l + b)
= 2 × (12 + 8)
= 2 × 20
= 40 m.
For Dolly’s House.
Length, l = 15 m
Breadth, b = 5 m
Perimeter of the lawn = Fencing required = 2 × (l + b)
= 2 × (15 + 5)
= 2 × 20
= 40 m.
So total fencing = 40 + 40
= 80 m.
