Question

A rectangular yard measuring 24 ft by 44 ft is bordered (and surrounded) by a fence. Inside, a walk that is 2 ft wide goes all the way along the fence. find the area of this walk. Be sure to include the correct unit in your answer.

Answer 1

1 - First we can determine the area of the yard alone by doing:

22 feet x 44 feet = 968 feet squared

2 - Then, we can calculate the area of the walk by first subtracting two from the original values given ( 22 and 44 ), and then subtract the area of the yard with the value given in the equation we setup and solved below:

(22-2) x (44-2) = 20 x 42 = 840 feet squared

3 - Stated in step 2, subtract 840 from the yard's area ( 968 feet squared ) to determine the space that is left over, that'll represent the 'walk' in this case:

968 - 840 = 128 feet squared

4 - Final Answer:

The area of the walk is 128 feet squared.
