Question

The width of a rectangle is 13 inchs more than 5 times the length. if x represents the length, write an algebraic expression in terms of x that represents the perimeter of the rectangle. simplify the expression.

Answer 1

perimeter is 2L+2W

problem states width = 5L+13

so plug that in for w:

P=2L+2(5L+13)

 now simplify

P=2L+10L+26

P=12L+26
