Question

When Charlotte installed a fence along the 200 foot perimeter of her rectangular backyard, she left an opening for a gate. In the diagram below, she used x to represent the length, in feet, of the gate. What is the value of x

Answer 1

Answer:

 x = 10

Step-by-step explanation:

P = 2(60 + x) + 2(30) = 200

   = 120 + 2x + 60 = 200

        2x + 180 = 200

          2x = 20

            x = 10
