<PRE><B>Question 1107361</B>
Area (A) of triangle = (1/2) * base * height
:
base is 3x/2, where x is the height of the triangle
:
(1/2) * (3x/2) * x = 27
:
3x^2/4 = 27
:
multiply both sides of = by 4
:
3x^2 = 108
:
x^2 = 36
:
x = 6 or x = -6
:
we reject the negative value
:
base = 3*6/2 = 9 m
