Answer 4

Ok 2 questions whats with the lw and *?

Answer 5

* = multiplication

Answer 6

lw = Length * Width

Answer 7

oh lol.. ok...

Answer 8

5x2=10 or 5*2=10 ;). So thats the area?

Answer 9

wooops LOL FORGOT ITS 12 XD (embarrassed)

Answer 10

5x12 = 60

Answer 11

Yes..

Answer 12

Now subtract the area of the triangle.

Answer 13

Subtract 12 - 8 to find the base..we already have the height (5)

A = 1/2 * b * h

Answer 14

Half times b,h? 0_0

Answer 15

Yes..that's the formula for the area of a triangle.

Answer 16

b = base
h = height

Answer 17

.-.

Answer 18

@OpenStudyRocks5* So..12 - 8 = ?

Answer 19

The heights 8? I thought it was 5

Answer 20

5..yes..but we have to subtract 12 - 8 to find the base.

Answer 21

Whatever your the honorary Professor. 12 - 8 = 4 :D

Answer 22

@iGreen

Answer 23

Lag..hold on.

Answer 24

Yes, so the base is 4, and the height is 5.

A = 1/2bh

A = 1/2 * 4 * 5

Answer 25

Simplify

Answer 26

Can you multiply 1/2 * 4 * 5? @OpenStudyRocks5*

Answer 27

Doesn't that equal 10? (since 4x5=20 and 1/2x20=10) ? or am I doing it wrong?

Answer 28

Yes, it does.

Answer 29

Now subtract that from the area of the rectangle we got.

Answer 30

60 - 10 = ?

Answer 31

hold on lag killing me now.

Answer 32

50

Answer 33

Yes, that's correct.
