You can put this solution on YOUR website! Area of triangle = 1/2 L*H
base of X + 6, the height is X + 8
1/2(x+8)(x+6)= 60
1/2(x^2+14x+48)=60
multiply equation by 2
x^2+14x+48=120
x^2+14x+48-120=0
x^2+14x-72=0
x^2+18x-4x-72=0
x(x+18)-4(x+18)=0
(x+18)(x-4)=0
x=-18 OR 4
ignore negative because the length and height cant be negative
x=4
plug x=4
base = x+6 = 10 units
height = x+8 = 12 units
CHECK
1/2 * 10*12= 60
