Solve and explain, because i do not get the question

Area of a triangle:

A= 1/2bh

We need to find something that equals 25, with the base being twice as big as its height.

25= 1/2bh

The base and height multiplied together have to equal 50 since the area is half the base and the height.

10*5= 50

10 is two times 5.

It equals 50.

50*1/2= 25

So, the height is 5.

I hope this helps!
