Expert Answer
Here, let us assume the base of the triangle be b.
Given that ,
Altitude (h) = 2 x base (b) = 2b
Also, area of the triangle = 36 m2
Substituting the known values in the formula for area:
Area = 
x b x h
36 = x b x 2b
b2 = 36 = 62
or b = 6
Thus, the base of the triangle = 6 m
And, the height of the triangle = 2 x 6 = 12 m
