Must two quantities have the same dimensions when subtracting them?
Yes they must be in the same units of measurements.
What is the condition for the addition of matrices?
The matrices must have the same dimensions.
Must two quantities have the same dimensions if you are subtracting them?
Yes.
Why is adding subtracting and equating quantities possible only if they have the same dimension?
If they are not on the same dimension then you cannot do this. They will be different numbers and will not go together.
What is the length and width if the perimeter is 168?
You can't tell the dimensions from the perimeter. There are an infinite number of rectangles, with different dimensions, that all have the same perimeter. If it's 168, then the only thing you can be sure of is that the length and width add up to 84, but you can't tell what either of those dimensions must be.
If all the terms in an equation have same units then is it necessary that they have same dimensions?
if they have same units they must have same dimensions . but thy can have different units even if they have same dimensions i hope it helps :
What must be true in order to add matrices?
They must have the same dimensions.
Must two quantities have the same dimensions when subtracting them?
Yes they must be in the same units of measurements.
Must two quantities have the same dimensions if you are multiplying them?
No
Must two quantities have the same dimensions?
If you intend 'dimensions' to mean units then whenever the two quantities are to be operated on each other then they must have the 'dimensions', refer to dimensional analysis
What is the condition for the addition of matrices?
The matrices must have the same dimensions.
Must two quantities have the same dimensions if you are subtracting them?
Yes.
Is it true that two quantities having the same dimensions must be measured in the same units?
No, it is not true.
Why is adding subtracting and equating quantities possible only if they have the same dimension?

Is the length and the dimensions is the same?
Length is one of the dimensions. Length, width, height etc. which can describe an object are called its dimensions.
