The length of the base of a triangle with
constant area varies inversely as the height.
When the base is 18 cm long, the height is 7
cm. Find the length of the base when the
height is 6 cm.

The length of the base when the height is 6 cm is 21 cm .In the question , it is given that ,the length of the base(b) of the triangle varies inversely with the height(h) ,which is represented as b ∝ 1/hb = k/h where k is the constant of variationgiven that when b = 18 , h is = 718 = k/7k = 18 × 7k = 126Substituting , the value of k = 126  in the equation b = k/h  , we get ,b = 126/h So, the length of the Base When h = 6, b = 126/6b = 21Therefore, the length of the base when the height is 6 cm is 21 cm .Learn more about Equations here https://brainly.com/question/1758955#SPJ1
