Me what is the area of a trapezoid with a top base of 10in., bottom base of 13in., and a height of 12in.? enter your answer in the box

Start by identifying the formula for the area of a trapezoid.
This is: A=a+b/2 (h)

Next, identify your variables that you are able to plug into the formula. A and B are the bases. So:
a- 10 in
b- 13 in
The height is also given in the problem. This value is 12.
So:
h- 12 in

Now you can plug them into your formula and rewrite it. It should look something like :
A = 10 + 13/2 (12)

After that, add the a and b values together and then divide that number by two.
This should look like:
A = 23/2 (12)
A = 11.5 (12)

Finally, multiply to find the total area.
This results in:
11.5 x 12 = 138

So your final answer for the area of the trapezoid is 128 inches^2

Don’t forget your proper area units!
I hope this helps! :)
