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!
