The formula for the area,A, of a trapezoid is shown below, where ݄H represents its height and b1 and b2
represent the lengths of its bases.  For this problem, let b1 represent the length of its shorter base.

A=1/2h(b1+b2)
which of the descriptions below is equivalent to the formula shown above?



Answer :

One equivalent is [tex]A=h( \frac{ b_{1}+b_{2} }{2}) [/tex]

Another example is [tex]A= \frac{(b_{1}+b_{2})(h)}{2} [/tex]
