PLZ HELP!
What is the area of this trapezoid?
Enter your answer in the box.

80 units^2

Step-by-step explanation:

area = (height)(base) for rectangles

area = 1/2(height)(base) for triangles

3x8 = 24    for rectangular portion

1/2(7)(8) x 2 = 56   for both triangular portions

24+56 = 80

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
