Answer: 4.5 meters is 45 centimeters.
Step-by-step explanation: The centimeter is just a single digit behind a meter, or in more mathematical terms, a tenth of a meter.
In this case, you can simply multiply 4.5 by 10 or divide 4.5 by one hundreth (or 1/100). In doing so, you'd successfully acheive the value of 45. Study your conversions
