Answer 2

like?

Answer 3

break them into two.

Answer 4

you need to find the area of one triangle and then the other and then add the two areas together

Answer 5

actually if the triangles are congruent it is just A=bh
because ewach triangle individually is A=bh/2

Answer 6

ok so if i broke ABC apart would the H still be 20?

Answer 7

yes

Answer 8

so each triangle is B = 20 and H = 20

Answer 9

These two are congruent so adding the extra triangle makes this a rhombus. Like I said 2(bh/2)=bh=A, just like a rectangle.
