Agarden that is 5ft. by 6ft. has a walkway that is 2.5ft. wide around it. find the amount of fencing needed to surround the walkway

Hence, the amount of fencing needed to surround the walkway is:

42 ft.

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.

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
