Math triangular flag

Question

The area of a triangular flag is 42 square Centimeters it’s altitude is 2 centimeters Longer than twice its base find the Lankes of the altitude and the Base

Answer 1

h = 2b+2

area = hb/2 = (2b+2)(b)/2 = b^2 +b = 42

b^2 +b -42 = 0

(b+7)(b-6) = 0

b = 6 cm = base

h=14 cm = altitude

ignore the negative solution
