The perimeter of a rectangle is p feet. Find the length L and width w if the length is k more than the width. Show the first two steps, step one is just choosing a variable and represent both length and width in terms of that one variable. In step two substitute those values from step one into the formula for perimeter.


;
k=10
p=180

Simple substitution: ;




Now you can substitute the given values for p and k to evaluate w. Use this found value to evaluate L.
