Question

how do you find the area of an equilateral triangle if it has 14 inch sides?????????

Answer 1

A = 1/2bh

1/2(14) = 7

(7)(14) = 98

I think this is how you do it, but I'm not sure.

Answer 2

If all they give you is the length of the sides, you cant use the 1/2bh formula because you dont have the height.
Instead you can use the formula sqrt(3)/4(l)^2 where l=length (14 in this case)

Answer 3

Oh, okay. Sorry, I actually haven't done such problems.

Answer 4

thanks guys for the help! @steffw and @a1234
