Perimeter is the outside length of an object...three-d or not. So, if you want to find out the outisde length of an object/perimeter, you will have to know the measure of one or two sides (depends on a shape) and add it.

The inverse operation of addition is subtraction. The inverse multiplication by a number other than 0 is division. Multiplication by 0 does not have an inverse operation.

OPERATION
Yes it is : a + b = b + a for all integers a and b. In fact , if an operation is called addition you can bet that it is commutative. It would be perverse to call an non-commutative operation addition.
perimeter is adding the lengths of the sides together
The operation is called addition.
No. Addition and subtraction are the last operations, done on a left to right basis as they have equal precedence. See the related question below.
what is the commutative operation of addition
The inverse operation of addition is subtraction. Subtraction undoes addition by taking away a number from the sum to return to the original value.
Subtraction is the inverse operation to addition. Multiplication is repeated addition.Division is the inverse of multiplication.
Only by the definition of a perimeter.
addition +
any operation
Addition is the inverse operation to subtraction.
Anyone who has mastered the measurement of lengths and simple addition can find the perimeter of a plane shape.
An inverse operation undoes the effect of another operation. For example, addition is the inverse operation of subtraction, and multiplication is the inverse operation of division. Applying an operation and its inverse leaves you with the original value.
