Arectangles width is one third it’s length, and it’s perimeter is 120 m. find the dimensions of the rectangle

The length is 45m and the width is 15m. Hope I was able to help

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
