This can be solved using proportion then cross-multiplying. Let Jackson's shadow be X, and we are going to make a proportion with this. If you take the tree's length and divide it by the tree's shadow, it should be proportional to the quotient of Jackson's height and shadow. So we have the equation of 6/10.8=1.2/x, this we can easily solve by cross multiplying, and we get the answer of 2.16 meters.
