Answer:
340.8cm^2
Step-by-step explanation:
So surface area is basically the area of all the sides combined. And we know that the area of a triangle is 1/2bh, and for a rectangle it is LW. So there are three congruent rectangles, and one of those rectangle's area is 72 ( 6 x 12), so you can multiply that by 3 to find all three rectangles, which is 216. We also know that the two triangles are congruent. and the base is 12, and height is 10.4, so 12 x 10.4 is 124.8.
We take the total of the rectangles and the triangles to find the total surface area:
216 + 124.8 = 340.8cm^2

Answer:
Angle bisectors
Let’s first remember how to construct angle bisectors. First you draw a circle with center in a vertex of your angle and arbitral radius. From the points you got as intersections with your circle and arms of angle, you construct another two circles. Draw a semi line that goes through vertex and intersection of those two circles and you bisected your angle.
After knowing to construct angle bisector, people started wondering what would happen if they drew all three angle bisectors in a triangle. Will they intersect in the same point and what would that mean. So let’s try constructing it.
