The eiffel tower is a French monument built by Gustave Eiffel in 1889 for the world exhibition in Paris and was originally to be dismantled after it

Since its opening to the public, it has welcomed over 300 million visitors

Calculations

A person who is 175 cm tall stands in front of the Eiffel Tower so that his shadow and that of the Eiffel Tower are at the same point in O

Calculate the Eiffel tower’s height to the nearest meters

We use the Thales theorem that is A/B is equal to C/D because the person and the Eiffel tower are parallel

497/2,7 is equal to C/1,75

184,0741 is equal to C/1,75 so, 184,0741=C/1,75

I multiply each side by 1,75

322,1296=C so the Eiffel tower’s height is 322 meters
