78. you can find the area of the two ends which are triangles by subtracting 11 from 15. Then divide that four by two since both ends are included. Multiply 2 by 6 to get half the area of one triangle. But since there are two just leave that number as is. Finally multiply 11 by 6 to get the rest of the area.

Answer:

A=78ft

Step-by-step explanation:

The area of a trapezoid is A=(a+b)/2 *h

a=long base

b=short base

h=height

For your trapezoid, it will look like this:

a=15ft

b=11ft

h=6ft

Let's add those into the equation:

A=(15+11)/2 *6

Okay, let's solve it! Using PEMDAS, we know parenthesis are first.

A=26/2 *6

Now we divide!

A=13*6

Multiply! And don't forget to add your unit.

A=78ft
