The Formula to find the area of a Trapezoid is...
A=(b1+b2)h
-Divided by-
2
Base1 for this trapezoid is equal to 2in+12in+5in
Do you see where I got 12 from?
Line AB is = to ine FE
AB=12in
FE=12in
So...
Line DC=19in in total
A=(19+b2)h
Line AB=12
A=(19+12)h
The height is = to 9in
A=(19+12)9
So...
19+12=31
Times 9=279
279÷2= 139.5
The area of this Trapezoid is 139.5
