Answer:

Trapezoid:


A=(1)/(2)h(b_(1)+b_(2))

Rhombus:


A=(1)/(2)d_(1)d_(2)

Triangle:


A=(1)/(2) bh

N-gon:


A=n*(1)/(2) as\\\\A=(1)/(2) ap

Explanation:

In the trapezoid, h is the height and b is the base.

In the rhombus, d is the diagonal.

In the triangle, b is the base and h the height.

In the n-gon, n is the sides of the n-gon, a is the apothem, s is the side, and p is the perimeter.
