Okay, here we have this;

Considering the provided graph, we are going to calculate the requested height, so we obtain the following:

So to calculate the height of the trapezoid, we will replace in the area formula with the given information, so we have:

A=(b1+b2)h/2

10 ft²=(7ft+3ft)h/2

10 ft²*2=(10 ft)h

20 ft²=(10 ft)h

h=20 ft²/10 ft

h=2 ft

Finally we obtain that the height of the ramp is 2ft, then the correct answer is the second option.
