Answer:
324
Step-by-step explanation:
If you want the area of the entire trapeziod.
The formula for area of a trapeziod is:
1/2h(b₁+b₂)
So the equation applied to the trapeziod is:
2.5(20+12)
20+12 is 32. 32 multiplied by 2.5 is 80.

Ｙｏｕｒ ａｎｓｗｅｒ ｉｓ ８０.</em></u></h3>
Step-by-step explanation:
Here
BC=P=10
AC=B=b
AB=H=15
then using fourmula
h^2= p^2+ b^2
b^2= 15×15 - 10× 10
b^2= 125
b=11.2
Multiply the top and bottom.
3/8 * 16/7 = 48/56
Simplified: 5/7
