Answer
45 cm
Explanation
We are told that the diameter of the handle on a broomstick is 3.75 centimeters.
We are then told that if 12 of these broomstick handles are laid side by side (an assumption because the image of the brromsticks isn't given), qhat is the length of all these diameters.
1 diameter = 3.75 cm
12 diameters = 12 × 3.75 cm = 45 cm
Hope this Helps!!!
