Question 668504: Please help we with this problem, solving equations using systems of equations. Thank you.
The perimeter of a tennis court is 228 feet. After a round of tennis, a player's coach estimates that the athlete has run a total of 690 feet, which is equivalent to 7 times the court's length plus four times its width. What are the dimensions of a standard tennis court?

Hi,

 2L + 2W = 228      || Mulitplying 1st EQ by -2 and adding to 2nd

 7L + 4W = 690

     3L = 234

      L = 78'   and W = 36'
