Respuesta :

It usually works to use the formula for the area of a trapezoid.
  A = (1/2)×(b₁ +b₂)×h
where b₁ and b₂ are the lengths of the parallel bases, and h is the height (the perpendicular distance between the bases)

_____
This is one of several area formulas it pays to memorize.

Answer:

add the parallel sides and divide by 2

then multiply it by the perpendicular side so  

Step-by-step explanation:

A=side one+side two x2
