Question

Can someone please help me? I really need help with this. Iwill give a medal.

Find the area of the following shape. You must show all work to receive credit.

Answer 1

Think you can take a picture or draw the shape?

Answer 2

Okay. If you're ever given something that seems unnecesary complicated, always try to take it down to something very simple.

If you were given a similar problem, but it was just a rectangle or a triangle on a similar grid, could you do it?

Answer 3

uhh maybe. would it just be multiplying the sides?

Answer 4

if that is the case then can't i just make that one shape in 2 shapes.. and find out the different areas?

Answer 5

Right. For a rectangle to get the area you multiple the side lengths. For a right triangle you multiple the side lengths and divide by two

Does this picture help at all?

Answer 6

If you can find the area of each individual shape and add them up, you'll get the whole area

Answer 7

So for the rectangle it would be 6x6=36 right?

Answer 8

Yep! 36 units squared

Answer 9

and for the triangle i would do... 3x3 divided by 1/2? which would be 4.5?

Answer 10

Which triangle are you looking at? I think you might've miscounted the side length

Answer 11

the one you drew.... of wait. it's 4 x 6. my bad. and then the answer would be 12?

Answer 12

Okay hold on

Answer 13

Answer 14

That triangle is 3 by 4. Does that make sense?

Answer 15

ohhhhhhhh okay, nvm omg. I was doing it the wrong way, yeah. i get it. Then it's 6.

Answer 16

so then the final answer is 42. okay

Answer 17

Thank you!!!!!

Answer 18

Wait. There are two other triangles

Answer 19

wait wut .-.

Answer 20

Answer 22

Sometime's it's important to look back at the bigger picture. There are 3 triangles and one rectangle

Answer 23

so...
3x4 div by 1/2= 6
3x6 div by 1/2= 9
6x6 div by 1/2= 18

Answer 24

and for the rectangle it would be 6x6=36

Answer 25

and the final answer is..........69 :) am I right?

Answer 26

Oh sorry. Umm, where are you seeinga 6x6 triangle?

Answer 27

Oh. Keep in mind that you only look at the bases of a right triangle for its area. So a triangle that looks like this

http://puu.sh/ie16I/1549b72568.png

Has bases 1x6, so it's

6x1 div by 2= 3

Answer 28

Other than that I think it looks good

Answer 29

Should be 54 rather than 69

Answer 30

i thought it was 56? not 54...

Answer 31

Oh maybe I added wrong 1 sec

Answer 32

36+6+9+3

36+6 = 42

42+9 = 51

51+3=54

Answer 33

If I'm making some dumb arithmetic mistake feel free to point it out

Answer 34

ohhh okay, sorry nvm

Answer 35

Thank you for your help!!

Answer 36

Okay. Any questions about what we did? Does each step make sense?

Answer 37

Sum the area of triangle ABF and trapezoid EBCD.
