The two parallel bases b1 and b2 are
b1 = 12
b2 = 9
the order of which base you pick doesn't matter

The height is h = 10 and it's perpendicular to each base.

The area is...

A = (1/2)*h*(b1+b2)
A = (1/2)*10*(12+9)
A = (1/2)*10*(21)
A = 5*21
A = 105

Final Answer: B) 105 square centimeters

The following octagon is formed by removing four congruent right triangles from a rectangle. What is the area of each triangle?
3241004551 [841]
Answer:
2 cm squared

Explanation:
The question asks for the area of each small triangle in the corners(meaning 1 triangle, not 4) as shown from the dotted lines. The area of a triangle is found by (base*height)/2.
Looking at the diagram, the triangle is 2 cm for both the base and height, and the hypotenuse is not labeled. Because it is a right triangle, 2 cm is also the height(the height is defined as an altitude from the tip of the triangle to the base using a right angle). So, height=2 and base=2.
Plug these numbers into the formula bh/2.
bh/2=?
(2)(2)/2=?
4/2=?
2=?
Each triangle has an area of 2 cm squared.
