Find the area of each figure with the given dimensions
Trapeziod: b1 = 6,b2=10, h=5
Trapeziod: b1= 4.5, b2= 8, h=6.7
I wasn't in school the day we studied this, and i am only in 7th grade!

the formula for area of a trapezoid is A = h (b1 + b2) all over 2. So, for the first trapezoid, you would have:
5 (6 + 10) / 2 = 40. For the second trapezoid, you would have:
6.7 (4.5 + 8)/ 2 = 94.6375 
52

Why is a parallelagram never a trapezoid
