The formula is quite long. You can find it here:
http://en.wikipedia.org/wiki/Trapezoid
Here is the solution:
a=25
b=15
c=10
d=13
A=(35/20)*squareroot(43*13*17*13)
A=(7/4)*351.5=615cm^2.

B = 25
b = 10
A = [(B + b)*13] /2]
A = [(25 + 10)*13/2]
A = [35*13/2]
A = 227,5cm²

The formula is : 1/2 X h (b1 + b2)
Hope you will rate it as the best answer.
