a scale model of a double decker bus is 7.0cm high and 15.4cm long. if the bus is 4.2m high how long is it

9.24 m

Step-by-step explanation:

Dimensions of the scale model:

Dimensions of the real bus:

The ratio is:

Then:

The length of the bus is 9.24 m

d

step-by-step explanation:

i used the pitagoras theoreme

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
