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.
