Gilberto Gross · Answer 1

4.2 meters

Step-by-step explanation:

The height that the lights will be put is 420 centimeters, and the question asks how many meters off the ground the lights need to be placed, so to solve the question we just need to convert 420 centimeters to meters.

We know that 1 meter is equal to 100 centimeters, so we can solve this using a rule of three:

100 centimeters - > 1 meter

420 centimeters - > X meters

100/420 = 1/X

X = 420/100 = 4.2 meters

The lights need to be placed on the pole at 4.2 meters off the ground.
