Find the length of the altitude of an equilateral triangle of side 3√3 cm.	Choose the correct choice from the following options
A) 4.5cm
B) 7.2cm
C) 4.3cm
D) 5.6cm
E) 5.7cm
Area of the triangle = (√3/4) x (3√3)2 = 27√3. Let the height be h.   Then, (1/2) x 3√3 x h = (27√3/4) X(2/√3) = 4.5 cm.   4.5cmns: 4.5cm
