HOPE THIS HELPS
1. find the area of the two triangles, including the shaded section. the formula for this is a=1/2bh
the height and base are both 24 inches. this is because you add the 10 from the side of the square to the 14 that is given
so:
a=1/2(24)(24)
a=(12)(24)
a=288 sq. inches
since there are two triangles, you would multiply the area by 2
a=2(288)
a=576 sq. inches
now, since you only need the unshaded section, you have to take away the shaded section, which is a square. to do this, you must calculate the area of the square and take it away from the area of both triangles.
a=576-(lw)
a=576- (10)(10)
a=576-100
a=476 sq. inches
that is your answer

hope this helps with the work and it not that much so you good but a radius of 7 the circumference would be 43.98 not 43.96 but the other ones are completely wrong
Answer:
Selling Price of the Book - $7.70
I believe that this is the answer
Step-by-step explanation:
We need to find what is 40% of 5.50.
40/100 x 5.50
After solving this, we will get 2.20
Now, the question is asking what is the selling price of the book will be after it is marked up. Marked up means an increase in price, and the increase in price is 40% of 5.50 which we have already found. All there is left for us to do is add 5.50 and 2.2. This will give us $7.70.
