Answer:
B. [tex](15-4)(14-6)[/tex]
Step-by-step explanation:
We are given that,
The dimensions of the bigger rectangle are 15 ft × 14 ft.
That is, Length = 15 feet and Width = 14 feet.
So, we have that,
Length of the shaded rectangle = (15 - 4) feet
Width of the shaded rectangle = (14 - 6) feet
Then, the area of the shaded rectangle = Length × Width
Thus, option B is correct.
