Solution
In order to find the total length of fencing around both the gardens, we will calculate the perimeter of both the gardens and then add them.
Given, size of lawn in front of Molly’s house = 12 m × 8 m
Perimeter = 2(Length + Breadth)
= 2(12 + 8) m
= 2(20) m
= 40 m ...(i)
Now, size of lawn in front of Dolly’s house = 15 m × 5 m
Perimeter = 2(15 + 5) m
= 2 × 20 m
= 40 m ...(ii)
From equations (i) and (ii), we get
Total length = 40 + 40 = 80 m
Hence, total length of bamboo fencing is 80 m.
