A. 32 ft
B. 44 ft
C. 64 ft
D. 84 ft

Answer 1

Chris will need to buy 64 feet of fencing to enclose a rectangular space with dimensions of 22ft by 10ft.

Step-by-step explanation:

The subject of this question is Mathematics, and the grade level is Middle School. The question involves calculating the perimeter of a rectangle, which is a basic concept in geometry. Chris wants to place fencing around a rectangular space that measures 22ft by 10ft.

To find the amount of fencing needed, we need to calculate the perimeter of the rectangle. The formula to calculate the perimeter (P) of a rectangle is:

P = 2(length + width)

Plugging in the dimensions of the rectangle:

P = 2(22ft + 10ft) = 2(32ft) = 64ft

Therefore, Chris will need to buy 64 feet of fencing, which corresponds to option C.
