Trapezoid Area Formula. According to the trapezoid area formula, the area of a trapezoid is equal to half the product of the height and the sum of the two bases. Area = ½ x (Sum of parallel sides) x (perpendicular distance between the parallel sides).
b1: base 1
b2: base 2
b1 = 15m
b2 = 11m
a = 65m2
[tex]\begin{gathered} a=\frac{1}{2}(b1+b2)h \\ h=\frac{2a}{(b1+b2)} \\ h=\frac{2\cdot65}{(15+11)} \\ h=5m \end{gathered}[/tex]The height would be 5m
