Question

Quizplus · Accepted Answer

Using similar triangles, the height of the lamppost (h) and the person's height (6 ft) are proportional to the total distance from the lamppost to the tip of the shadow (24 ft) and the length of the shadow (10 ft). Thus, h/24 = 6/10, solving for h gives h = 14.4 ft, which is closest to 13 ft.
