Area of Triangles, Trapezoid, and Kite?

Question

ok so in class today we got the formula for each.

Triangle = B x H /2

Trapezoid = 1/2 (b+b(2) ) h OR (b+b(2) ) /2

Kite= 1/2(frac) d; d(2) OR d,d(2)/2

the numbers in parenthesis means squared.

Can you guys please help me out cause i dont know how to use they or what the h**l they mean, she just told us "figure it out" please help. On like what to do.

Answer 1

The triangle formula is one half times base times height.  The trapezoid formula is one half times base1 plus base2 times the height. The kite is one half times both of the diagonals.
