Use the formula: $$Area = b \times h$$Do you know how to do this?

anonymous · Answer

A= bh
A= 2*2.9
A= 4.58

Weird how the answer isn't there?

anonymous · Answer

it is 5.8

opcode · Answer

@kaytru 
$$Area = b \times h$$
$$Area = 2 \times 3$$
$$Area = 6$$

$$6.0 cm^2$$

anonymous · Answer

but it is bXh and tht is 5.8

anonymous · Answer

oh, multiplication was way off. Sorry! @TheOcean

anonymous · Answer

lol

anonymous · Answer

@Opcode The height isn't 3

anonymous · Answer

it is ok

opcode · Answer

@kaytru 
Why not? The picture shows that is is 3 though.

anonymous · Answer

it is 5.8 right? the total? cause BXH= 2.9X2=5.8

anonymous · Answer

@Opcode The dotted line is the height.

opcode · Answer

If you want a triangle then yes, the dotted line is the height. We want the height of the parallelogram though.

anonymous · Answer

@Opcode Um, no. The dotted line the height of a triangle or/and a parallelogram.

anonymous · Answer

the triangle is the parolelagram. it says: what is the area of THIS PAROLELAGRAM

anonymous · Answer

5.8 is the area of the parallelogram.

opcode · Answer

For something to be a parallelogram, the sides must be congruent. https://i.imgur.com/t1V1Rbu.png If you use the dotted line as your height the sides are not congruent. You won't be finding the area of a parallelogram...

op, it tells that it is a parallelogram, and then gives a picture
therefore it is a parallelogram :P
so  5.8 is correct :)

opcode · Answer

Why do we derive the height from the dotted line though? O_o?

anonymous · Answer

ummmm......... this question is klosed

jigglypuff314 · Answer

op, because there is a perpendicular square thing at the bottom of the dotted line

zale101 · Answer

because it shows the actual height , if the height would be the diagonal length line it would show more taller than it is actually

Jigg jigg that's a 90 degree angle >.>

opcode · Answer

My geometry isn't making sense to me any more...
I have faith in the green people though. 5.8 is correct.

the_fizicx99 · Answer

Op, do you have faith in me? O.o

zale101 · Answer

i do many mistakes in math, i recommend not trusting me >.<

the_fizicx99 · Answer

*Doesn't reply* I see >.>

opcode · Answer

I found the explanation of why we use the dotted line:
"The base and height of a parallelogram must be perpendicular. However, the lateral sides of a parallelogram are not perpendicular to the base. Thus, a dotted line is drawn to represent the height."
