What is the area of trapezoid DEFG with coordinates D (2, 3), E (5, 3), F (3, 1), and G (2, 1)? 2 square units 3 square units 4 square units 8 square units

Kyky232:

@AZ

AZ:

Before we plot the points, do you know the formula for the area of a trapezoid?

Kyky232:

no sir/ma'am/fam

AZ:

I like to use images because it conveys it better than I could with just words and it's easier to get the point across

We have to average the two bases and multiply it by the height Now, let's plot our points

Kyky232:

ok :)

AZ:

You do know how to plot points on a graph, right?

ha, desmos is the best lol

desmos is awesome

Kyky232:

anyway. Back to the teaching-

snowflake0531:

DE is 2 units long

snowflake0531:

GF is 1 unit

AZ:

Let's draw in the sides so you can see the shape better

Can you tell me the length of the bases and what the height is? You just have to count the blocks in between the points

Kyky232:

3 and 2

Kyky232:

I think

AZ:

What is what and we're missing one more value

Kyky232:

Oh so 3 is the top, 2 is the height, and 1 is the bottom (idk math words)

AZ:

We have two bases remember

AZ:

Good! Yes

AZ:

So now let's put those numbers into our formula \(\text{Area} = \dfrac{\text{Base}_1 + \text{Base}_2}{2} \times\text{Height}\)

Kyky232:

the area would be 4 units?

AZ:

3 and 1 are our two bases 2 is our height

AZ:

Spot on!

Kyky232:

woah I did that all mentally

Kyky232:

am big brain

AZ:

Well done :)
