Answer:
Hence, the amount of fencing needed to surround the walkway is:
42 ft.
Step-by-step explanation:
It is given that:
A garden that is 5 t. by 6 ft. has a walkway that is 2.5 ft. wide around it.
Hence, the fencing is to be done around a garden whose dimensions:
(5+2.5+2.5)ft. by (6+2.5+2.5)ft.
= 10 ft by 11 ft.
Hence, the amount of fencing which is to be done is equal to the perimeter of the garden.
We know that the garden with walkway is in the shape of a rectangle with:
Length=10 ft.
and width=11 ft.
Hence, Perimeter of garden=2(10+11)
=2×21
= 42 ft.
Hence, the amount of fencing needed to surround the walkway is:
42 ft.
