What is the area of this trapezoid?

To find the area of a trapezoid, you have to a+b divided by 2 times h.

So you would take 11+5 and get 16 divided by 2 which is 8. then multiply that by h which in your case is 6. So the area is 48

Hope this was helpful.

A=1/2(b1+b2)(h)
A=1/2(11+5)(6)
A=48 cm^2
