What is the area of the trapezoid with height 11 units?

Step-by-step explanation:

The area of a trapezoid is:

(Base + Base/ 2) x height.

1 Base is 16.

The other base is 34. (We find that by adding 16 + 9 + 9)

34 + 16 = 50.

50 / 2 = 25.

The height is 11, so 25 x 11 is 275.

Therefore the area of the Trapezoid is 275 units.

Hope this helps!

275 units

Hi, I can help.

First you want to find the area of the outside portions which are triangles.

Lets go over the formula to find the area of a triangle.

A = b x h x 1/2

or in full terms

Area = base x height x 1/2

So lets take the base and height we are given.

Base = 9

Height = 11

And lets plug it into the formula.

Area = 9 x 11 x 1/2

And solve a bit :

9 x 11

=

99

Now we can take 99 and multiply it by 1/2. (Which is really the same as dividing by 2. It is splitting a number in half.

99 x 1/2

=

49.5

This is the area of one triangle. And since we have 2 what we have to do actually multiply this by 2.

So:

49.5 x 2

=

99

The area of these 2 is 99 units.

Lets keep this in mind but also solve the rectangle in the middle of the two triangles.

This is easier as the formula is :

A = b x h

in full terms

A = base x height

So lets plug in the base which is 16 and the height which is 11 :

A = 16 x 11

And solve :

16 x 11

=

176

And now we add the two triangles (99) and then the area of the rectangle (176) to find the total area of the triangle.

99 + 176

=

275 units

I hope this helps!
