To solve the problem, we need to use the following formula:

where
A is the area of a trapezoid
a and b are the lengths of its two bases
h is the height
Let x be the shorter base.
Then the longer base is x+2
Substituting the following into the formula
a = x
b = x+2
A = 150
h = 10
we have

Solving for x, we have

So the shorter one is 14 meters long, the longer one is 16 meters long.
