Use a variable to represent the unknown quantity then write an equationfrom the given information. Explain how you arrived at your answer.1.The area of a garden is 160 m2. Suppose the length of the garden is 3 m morethan twice its width. What is the length of the garden?2.The length of a tarpaulin is 3 ft. more than thrice its width and its area is 126 ft.².What is the length of the tarpaulin?3.Mario and Kenneth work in a car wash station. The time that Mario takes inwashing a car alone is 20 minutes less than the time that Kenneth takes inwashing the same car.

1) Let    x=width   ;   2x+3=length
Given: A=160m²

Using the quadratic formula you will get
Therefore, length=

2) Let x=width   ;   3x+3=length
Given: A=126 ft²

Use x=6  ;  Therefore,

3) Rate of Kenneth =
Rate of Mario =
