The perimeter of a rectangle is 162 ft. The lenght is 3 more than twice the width. How do you find the dimensions of the rectangle? Algebra Systems of Equations and Inequalities Systems Using Substitution 1 Answer mimi · Stefan V. Sep 25, 2015 Answer: Width: #"26 ft"# Length: #"55 ft"# Explanation: Let the length be #l# Let the width be #w# #l = 2w + 3# #2(l+w) = 162# #2w + 3 + w = 162/2# #3w + 3 =81# #3w = 78# #w = "26 ft"# This means that #l = 2w + 3# #l = 2(26) + 3# #l = "55 ft"# Related questions How do you solve systems of equations using the substitution method?
