The desired perimeter of the rectangle is designated by the conditional variable “X”.
The second step, using the conditions of the example, we get the equation: X = 2 x (9/5 + 9/5 – 3/20).
Based on the results of solving this equation, we obtain X = 2 x (18/5 – 3/20) = 2 x (18 x 4 – 3) / 20 = (72 – 3) / 10 = 69/10 = 6.9 meters.
Answer: the desired perimeter of the rectangle is 6.9 meters.
