Question

Compute the area of a triangle with sides.

15 × 15 × 18

Answer 1

Cut it in half then do Pythagorean theorem: (sqrt) 15^2-18^2

Answer 2

then A=1/2 (bh)

Answer 3

A =1/2 (18 x h)

Answer 4

a triangle with two equal sides is an isosceles, which makes it a bit special.
if we divide all the sides by 3 (to get nicer numbers) we get 5,5,6
the triangle looks like this
