SOMEONE PLEASE HELP ILL BRAINLIST.

A child casts a shadow 1.3 m long. The distance from the top of the child’s head to the end of the shadow is 1.9 m. To the nearest centimetre, how tall is the child?

Respuesta :

Answer:

Height of the boy is 1.4 m and casts a shadow of 1.2 m

At the same time, a building casts a shadow of 5.4 m and suppose height of the building is x m

Then ratio of their heights and shadows are in proportion

⟹1.4x=1.25.4

⟹x=1.21.4×5.4

⟹x=6.3

Hence, height of the building is 6.3 m.
