Question

Find the area of quadrilateral ABCD in each case. HElp PLEase ASAP

Answer 1

PLEASE MARK BRAINLIEST!

Answer:

Let's see...

Step-by-step explanation:

*Note: we can't find the exact area of the shaded figure right off the bat, we have to find the area of a bigger figure and divide it by 2.

The coordinates of the bigger figure:

A = (0,0)

B' = (0,4)

C = (5,4)

D' = (5,0)

Note: the little [ ' ] next to the B and D indicate that it is not the same coordinate as B and D, just that those points would be the same as point B and D.

That being said, what is the area of the bigger figure?

A =  l * w

A = 4 * 5

A = 20 units²

Now, divide the Area by 2:

A = 20 ÷ 2

A = 10 units²

I hope this helps!

Answer:

Please crown brainliest :) ^-^

12

Step-by-step explanation:

You would get 12 if you multiply the base- 3

And the height- 4

and then you get 12...The other answer is incorrect because you do not need to divide by 2.
