Write the formula for the area( A) of a trapezoid. Use b1 and b2 for the lengths of the bases, and use h for the height. A=

The general area formula for a trapezoid is the following equation:

 

\(A_{\text{trap.}}=\frac{1}{2}(b_1+b_2)h\)

 

A = area of the trapezoid

b1 = the length of a base

b2 = the length of the other base

h = the perpendicular height from one base to the other

 

Generally, it helps me to remember the formula as the quantity of the average of the lengths of the bases all multiplied by the height. For some reason, I can recall a formula better when I remember the formula, in words, and then translate it into an algebraic equation.
