long. At the same time the actualC.N.Tower
casts a shadow 123.3 m long. How high is the
C.N. Tower?

Answer 1

Answer:

we can proceed by taking x as the height of the model Tower and actual tower as y

when, x=0.9m y =?

x=0.2m y =123.3 m

By cross multiplying we get

» 0.2m × y = 0.9m × 123.3m

y = 0.9m × 123.3m

0.2m

= 0.45 × 123.3m = 55.485m
