The perimeter of a rectangle is 420 yd. if its width is six times its length; what is the area of the rectangle?

If the perimeter of a rectangle is 420yd, then the width is 18" and the length is 30. This is because 180 is 6 times of 30 and all of the sides combined total 420 yards. When you multiply 180 and 30, you get 5,400. The area of the rectangle is 5,400 square yards.

Sin(a)+cos(a)+cot(a)-1=2(csc(x)+1)
