Ответ:
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
The area of the walk is 128 feet squared.
