The length of a rectangle is twice its width. The perimeter of the rectangle is 133 feet.

2x + x+ 2x + x= 133

6x = 133

133/6= x

x= 22.1666667

Let the width of rectangle = l

Therefore, Length of rectangle = 2l

Perimeter of rectangle = 2( l+b)

133 = 2( 2l+l )

133 = 2×3l

133 = 6l

6l = 133

l = 133/6

l = 22.1666667

Width = 22.1666667

Therefore, length = 22.1666667 × 2

= 44.3333334

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
