Question

What is the area of the trapezoid below?

16 square units
18 square units
20 square units
24 square units

Answer 1

The formula used to find the area of a trapezoid is:
(a+b)(h/2)=A
Let's find the measurements.
The height is 4 units. Let's fill that in.
(a+b)(4/2)=A
Let's look at base one (top).
It's three units.
(3+b)(4/2)=A
Let's find our final measurement, the bottom base.
It's 6 units.
(3+6)(4/2)=A
Let's find the area.
9×2=18
I also have a drawing to show you the area.
The area is 18 units².

Tell me if this helps!!

Answer 2

The area of a trapezoid is found by the formula

`(1)/(2) h(b1 + b2)`
In this case, the height, h, is 4 units, the top base, b1, is 3 units, and the bottom base, b2, is 6 units. Our equation now looks like this:

`(1)/(2) (4)(3 + 6) \\ = 2 * 9 \\ = 18`
Therefore, the area of the trapezoid is 18 units.
