The length of the third side is about 7.81 inches and the perimeter of the triangle is about 18.81 inches
I'm writing out steps and a graph now to see if I can help explain it.
3x^2 / 4 = 48
Multiply both sides by 4 to get rid of the four on the left.
3x^2 = 192
Divide both sides by 3
x^2 = 64
The square root 64 to get x
Remember there are two answers
x = 8 and x = -8
Um... i cant help if there are not any question...
