The length of a tennis court is 78 feet. This is 3 less than 3 times the width of the court. What is the width of the court?
Answer (2)
l e n g t h : l = 78 f t . w − w i d t h l = 3 w + 3 3 w + 3 = 78 / − 3 3 w = 75 / : 3 w = 25 ( f t . ) ← an s w er
The width of the tennis court is 27 feet, calculated from the relationship between length and width provided in the problem. We used the equation 78 = 3 w − 3 to find this result. By isolating w , we determined that w = 27 ft .
