For a triangle the area is given as:
[tex]A=\frac{bh}{2}[/tex]

Re-arrange / solve for 'h':
[tex]h=\frac{2A}{b}[/tex]

Substitute known values:
[tex]h=\frac{2(60m^{2})}{15m}[/tex]

Compute:
[tex]h=\frac{120m^{2}}{15m}[/tex]
[tex]h=8m[/tex]

The area of a triangle is the base times half the height. 
If we reverse that, half the height is 60 / base, ie., 60/15 = 4.
This means the height is twice that, 8m.
