help with area please

OpenStudy (fuzzybird):

OpenStudy (kdr1308):

First find the area of the triangle, do you know the formula?

OpenStudy (fuzzybird):

1/2 x bh right?

OpenStudy (kdr1308):

Yeah or b x h div by 2

OpenStudy (fuzzybird):

okay, so my answer would be 24 right? @Kdr1308

OpenStudy (kdr1308):

Hold on.

OpenStudy (kdr1308):

How did you solve it? did you do 9 * 6 div by 2?

OpenStudy (fuzzybird):

no, I did 12x 4 x 1/2 there is no 9 in the problem.

OpenStudy (fuzzybird):

I am very confused.

OpenStudy (kdr1308):

Let me draw it....

OpenStudy (johnweldon1993):

Split it into 2 shapes |dw:1457473475421:dw|

OpenStudy (kdr1308):

Thanks @johnweldon1993

OpenStudy (johnweldon1993):

Now notice the triangle has a base (5 + 4) And no problem @Kdr1308 I'll let you continue :)

OpenStudy (kdr1308):

Alright, @fuzzybird you understand now?

OpenStudy (fuzzybird):

oh! I get it now! so the answer for the area of the triangle is 27 right?

OpenStudy (kdr1308):

Correct! Now we need to find the area of the rectangle

OpenStudy (fuzzybird):

30, because to find area's of rectangles its 6x5.

OpenStudy (fuzzybird):

- to find the area

OpenStudy (kdr1308):

Great, so add them together to get the total area

OpenStudy (fuzzybird):

so added together it's 57 correct?

OpenStudy (kdr1308):

Yep 52 in^2

OpenStudy (fuzzybird):

i'll medal @Kdr1308 & @Kdr1308 you medal @johnweldon1993 thank you so much! my teacher rushes through things waaaaay too fast and I got really confused.
