The perimeter is the distance around an object. the perimeter of a square is 84 centimeters. what is the length of one side of the square?

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
