so the formula for the area of a trapezium is
area = (a + b)/2 * h
*a is the short side
* b is the long side
*h is the height
so let's plug in the values we already know: area, long base, short base. Here's how the formula looks now...
6550 = (150 + 85)/2 * h
*so, we need to find 'h'
use algebra to find it.
6550 = (235/2) * h
6550 = 117.5 * h
6550/117.5 = h
h = 55.74 (approx)
