want to build a rectangular play space for her dog. She has 100 feet of fencing amd she wamts it to be 5 times as long as it is wide. What dimensions should the play area be?

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?
