0/0 because two thirds are lower then sixth rids unless u switch it then it would be 3/1
What are we supposed to be solving here?
Answer:
1. 375
2. 294
Step-by-step explanation:
Area of a trapezoid
A = 1/2 (b1+b2) *h where b1 and b2 are the top and bottom of the trapezoide
1.
A = 1/2 (14+36) *15
= 1/2 (50)*15
= 25*15
375
A = 1/2 (21+7) *21
= 1/2 (28)*21
= 14*21
294
