Step 1
Given that the length is 15g and the width is 2g+7
Now we know the area formula for a rectangular shape .
So using that area of the rectangular roof .
Step 2
From the area formula of a rectangular we know that if a and b are the given length and the width , then
area = ab
Now here given the length is 15g and the width is 2g+7 .
Therefore the area of the rectangular roof is
15g(2g+7)=(15g)(2g)+(15g)(7)
=30g2+105g
Therefore the answer is b. 30g2+105g
