h = b-4
b=b
a = 58.5 = b/2h

substitute the values...

callisto · Answer

Let b be the base of the triangle
From : The height of a triangle is 4 centimeters less than the base , we know that h = b-4
Area of triangle = (1/2)bh
                         = (1/2)b(b-4)
Since area is given to be  58.5 square centimeters
Therefore
 58.5  = (1/2)(b)(b-4)
117 = b^2 -4b
Can you solve it from here?
