How to find the area of an isosceles triangle and hexagon?
Hello, I would like some help on finding the area of two different shapes.
The first one is the area of an isosceles triangle with two sides of length 2x and one side of length x. Will someone show me the process of how to get this answer? The answer I got was:
But the book answer had 4 in the denominator.
As for my second area question, how would I find the area of a regular hexagon with sides of length x? The answer I got was:
But the book answer had this with 2 in the denominator.
With both of these, it appears that I must have forgotten to multiply it by 1/2 at some point, but I can't figure out when.
Help please? Thanks!
