Answer:
110 cm^2
Step-by-step explanation:
The first thing that you need to do is find the area of triangle AFE. The area of a triangle is always base*height/2. So in this case, that would be 10*6 divided by 2, which is 30 cm. Next, you will need to know the area of triangle ECB. Using that same formula, you will get 8*10/2, which is 40 cm. Finally, you will need to find the area of the whole rectangle. The area of a rectangle is always the length times the width. In this case, you would have 10*18, which is 180 cm. To get your final answer, you need to subtract the areas of the unshaded area from the whole area. That would be 180-(30+40), which is 110 cm. I hope this helped!

Answer: B. 15.7 inches
Step-by-step explanation:
The ramp forms a right angle triangle. The height of the ramp above the ground represents the opposite side of the triangle. The length of the ramp represents the hypotenuse of the right angle triangle. The base of the ramp represents the the adjacent side of the right angle triangle. Therefore, to find r, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
r² = 7² + 14² = 49 + 196
r² = 245
r = √245
r = 15.7 inches to the nearest tenth
