The base of a triangle is 6 cm longer than its height. If the area of the triangle is 140cm^2, what is the length of the base?

Im just confused on how the equation should be formed. Thanks.

B = H + 6

Area = HB/2

Substitute H+6 for B in the second equation and solve for H. Insert that value into the first equation to solve for B. Check by putting both values into the second equation.

140 = H(H+6)/2

70 = H^2 + 6H
