Ah... good ol' square roots...
Whenever you take the square root of multiplication or division, you can do the square roots separately. So, we can write:
This nifty truth allows us to easily find the answer:
All done!

The height or the distance between the two parallel sides of the given trapezium is 20 cm.
A trapezium or trapezoid is a two-dimensional geometric shape that has 4 sides, with one pair of parallel sides.
The parallel sides of a trapezium are called bases while the distance between them is the altitude or height.
The formula for the area of a trapezoid is given by
A = (a + b)/2 x h
where a and b are the parallel bases and h is the height.
Using this formula, the height or the distance between the two parallel sides can be computed.
A = (a + b)/2 x h
120 cm^2 = (5 cm + 7 cm) / 2 x h
120 = (12 / 2) x h
120 = 6h
h = 120 / 6
h = 20 cm
