Hmmm would like to see dat attachment.
OpenStudy (anonymous):
find the area
OpenStudy (anonymous):
Break it into 5 triangles. 1/2 base * height
OpenStudy (anonymous):
I did
OpenStudy (anonymous):
You know the base is 20, divide it by two to get it into a right triangle, in order to find height from base to middle.

You then use pythag theorem in order to get the height then solve.
OpenStudy (anonymous):
Wait you only know one length so how do you use pythagorean theorem?
OpenStudy (anonymous):
Just use the formula to save yourself time. A = 1.72 * x^2
OpenStudy (anonymous):
x being the length of one side.
OpenStudy (anonymous):
What do you get for the area? I get 688.2

688
OpenStudy (anonymous):
This only works if all the sides are the same.
OpenStudy (anonymous):
I have more like these coming up T.T
OpenStudy (anonymous):
Im sorry i made a mistake, break it into three triangles. So that two sides of the triangle are both 20.
OpenStudy (anonymous):
Then pythag.
