Area of Trapezoids

Area of Trapezoids

By Jamie [AMS]

The formula for the area of a trapezoid looks complicated...​

​

​The formula explained...

​

Step 1:

Add the bases.

​

The bases are the 2 sides across from each other that are parallel. You should always add them first.​

​

But you can solve it in 3 steps!​

Step 2:

Multiply the sum of the bases and the height.

​

Take the answer you got when adding the bases and multiply it by the height.​

​

But you can solve it in 3 steps!​

Step 3:

Divide the product by 2.

​

We do this because the formula says 1/2. When I multiply by 1/2 it is the same as dividing by 2.​

​

But you can solve it in 3 steps!​

Remember:

follow these 3 steps...

​Step 1:

​Add the bases.
