Question

The length of a rectangle is equal to three times its width. if the perimeter is equal to 240 ft. what is the length of the rectangle?

Answer 1

The answer would be 90 because if you put it into parts 1 part width then 3 parts and another 1 part width and 3 length length that would make 8 parts. divide 240 by the 8 parts gives you the width of 30. then you times that by 3 to get 90. hope that helped
