The ratio of a length of each equal side and the third side of an isosceles triangle is 3:4. If the area of the triangle is 18root5 square unit, the third side is

• Let base be t third side...
  and x be other 2 sides
  height={x2 - (b/2)2}1/2
  so, 18root5=(1/2)*b*root(x2 - b2/4)
  18root5=1/2 * b2 *root{(3/4)2 - (1/4) }
  on solving b=12
