We know the area is length * width.
So we know the length is 8 feet.
The width is 7 + x feet.
Multiply them:
8 * 7 + x.
56 + x.
So option D)
sorry, I misread the options! I meant D) not A)
Answer:
the answer will be D
Step-by-step explanation:
because (seven + x)*feet
the feet is 8 so
(7+x)*8
you distribute and it would be 56+8x
cause 8*7 is 56 & 8*x is 8x
so it would be D
