Answer: That would be the third option
Step-by-step explanation:
They want to know different types of areas
There are 4 pairs of overlapping triangles that I can see that are congruent. Two pairs share vertically opposite angles.
One more pair have right angles at the bottom of the rectangle.
One other pair have right angles at the top of the rectangle.
the area of the first shape is 4 times 12 which is 48 and the area of the second shape is 2 times 10 which is 20
48+20= 68 mi2
Hey there! I'd say the answer is 40π cm³
Why I say this answer?
Because if you take a close look at it you can see the angle of the shape and it's kind of obvious to me I hope this helped you! :D
