The height of a triangle is 7 cm longer than its base.

katrin [286]

A) Height -7 = base
B) .5 * height * base = 60
Substituting A into B
B) .5 * height * (height -7) = 60
B) .5*height^2 -3.5*height = 60
B) .5*height^2 -3.5*height -60 = 0
Using the quadratic formula:
Height = 15
Subtracting 7 gives us the base length
Base = 8
**************************************************************
Double-Check
.5 * 15 * 8 = 60

Let's recall that if the door and the window in it are similar rectangles, then we have:

60/84 = h/210

84 * h = 210 * 60

84h = 12,600

h = 12,600/

h = 150 cm
