Question 1173828: Perimeter of a garden - Application
Alan is planning to build a rectangular raised garden in his back hard. He has 18 feet of plastic edging that he wants use to build the perimeter of the garden. He knows that the Literal Equation for the perimeter of a rectangle is P=2L+2W where P=Perimeter,L=Length and W Width. But he is having trouble figuring out what length and width he should make the garden if he wants to use all of the plastic edging. Help Alan find the answer by completing the following steps:
Alan knows he has 18 feet of plastic edging to use for the Perimeter. He rewrites the equation as 18=2L+2W
.
Step 1: Solve and simplify18=2L+2W for. Write your answer as an equation:

Step 2: Use the new equation to complete the following table

Hi,

Alan knows he has 18 feet of plastic edging to use for the Perimeter. 

and knows 18=2L+2W

  2L+2W = 18

  2(L + W) = 18

    L + W = 9   (Various lengths and widths can be used as long as their sum is 9)

Using the Lengths Given:

  L  W

  6  3

Wish You the Best in your Studies.
