16ft long shadow of a building when the building true height is 40 ft 1 ft long shadow of a building when the building true height is 40/16 ft 2 ft long shadow of a person when the building true height is (40x2)/16 = 5ft (ans)

ratio: 40ft / 16ft = 2,5
soo.... x / 2ft = 2,5
answer: x = 5ft

The height of the person standing next to the building is 5 feet, calculated using proportions from the heights and lengths of their shadows. By setting up a proportion based on similar triangles, we found that H p ​ = 5 ft. Thus, the ratio of heights to shadow lengths is consistent, leading to this result.
