The length of a rectangle is four times the width. the perimeter of the rectangle is 45 inches. write a system of equations that represents this problem. what is the area of the rectangle?

Hello there,w= 1ul= 4uperimeter = l + l + w + w45 inches= 4u + 4u + 1u + 1u  10u = 45 inches1u = 45 inches/ 10      = 4.5 incharea= l x warea= 4.5 inch x (4.5 x 4)          = 4.5 inch x 18 inch        = 81 square inch  hope this : ))~top

The i'm not so sure though. this question could use a little more explanatory reasoning.

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?
