The area of a triangle is base * height
360 = b * h
Multiply each side by 2
720 = b * h
b = 5h
Substitute the value of B from the second equation into the first.
720 = (5h) * h
720 = 5
Divide each side by 5
144 =
Take the square root of each side
12 = h
.
The height is 12. The base is 5*12, or 60.
60 * 12 = 720
of that is 360.
