Question

The length of a shadow of the building is 36m. The length of the pole, which is perpendicular to the ground, is 1.9m. The length of the pole's shadow is 1.52m. What is the height of the building?

Answer 1

45

Explanation:

We are assuming that the pole's shadow and buildings shadow are proportional so our ratio is

x/36=1.9/1.52

cross multiply

1.52x=68.4

simplify

x=45
