Explanation:
The answer to the first question (the one about the cables): So you would solve it by adding the lengths of the cable together.
Cut off piece: 1.65 m Remaining cable: 3.5 m
To find the original length, we need to add the cut off piece and the remaining cable together.
1.65+3.5= 5.15
The original cable was 5.15 m long.
