what is the formula that you use bxh for?

OpenStudy (anonymous):

The Area of a triangle if i got the context right.

OpenStudy (anonymous):

the area of a triangle is bxh/2

OpenStudy (anonymous):

area of a triangle is (1/2)bh.

OpenStudy (anonymous):

b x h is a rectangle area?

OpenStudy (anonymous):

i thought that lxw was rectangle area

OpenStudy (anonymous):

oh right lolol, well a quadrilateral then.

OpenStudy (anonymous):

whats a quadrilateral

OpenStudy (anonymous):

i honestly have no idea

OpenStudy (anonymous):

parellelogram!

OpenStudy (anonymous):

are you positive or are you guessing because i need to know this for sure

OpenStudy (anonymous):

yes... it can be both..

OpenStudy (anonymous):

both?? both of what parallelogram and a rectangle

OpenStudy (anonymous):

A parallelogram is 2 triangles.

OpenStudy (anonymous):

its a parallelogram

OpenStudy (anonymous):

So can a rectangle.

OpenStudy (anonymous):

ok but can you bxh for a rectangle

OpenStudy (anonymous):

And you already know the area of a triangle. Just multiply by 2.

OpenStudy (anonymous):

or just a parallelogram

OpenStudy (anonymous):

its bxh for a parallelogram because its made up of 2 right triangles and a rectangle so when you multiply by b x h the half triangles are filled to be one... so its basically a big rectangle

OpenStudy (anonymous):

umm so can you use both lxw and bxh to calculate the area of a rectangle

OpenStudy (anonymous):

so is this true, can u

OpenStudy (anonymous):

L x W is for a rectangle and B x H is for a parallelogram which has slanted sides unlike a rectangle.. so there is a difference..

OpenStudy (anonymous):

Draw a parallelogram and draw a line from one corner to the other to convince yourself that it is actually two triangles. Same with a rectangle.

OpenStudy (anonymous):

ok now i get it
