Question

Bruce wants to find the perimeter of a rectangular plot of land. The length is (6x-29) km. The width measures (5x-17) km. What is the perimeter of the plot of land

Answer 1

Answer: Perimeter = 22x - 92

Units for the perimeter are in kilometers

==============================================

Work Shown:

L = length = 6x-29

W = width = 5x-17

P = perimeter of rectangle

P = 2*(L + W)

P = 2*(6x-29 + 5x-17)

P = 2*(11x - 46)

P = 2*11x + 2*(-46)

P = 22x - 92

If we knew the value of x, then we could find the actual numeric value for the perimeter. However, we don't have that info, so we leave it as is.
