the ratio between the perimeter and the width of a rectangle is 5 : 1 . if the area of the rectangle is 294 square centimeters , what is the length of the rectangle in centimeters ?
"perimeter = 2 ( w + l ) = 5 w 3 w = 2 l w = 2 l / 3 wl = 294 2 l ^ 2 / 3 = 294 l ^ 2 = 441 l = 21 cm the answer is c ."
divide(294, const_10)
