Maria makes a quilt. The main design is 5 feet long on each side. Then she adds a border around the main design. The finished quilt has an area of 36 square feet. By how does the border increase the total length of each side of the quilt

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?
