Rectangle A has 6 times the area of rectangle B. The width of rectangle A is 1/5 the width of rectangle B. The height of rectangle A is 20 inches. What is the height of rectangle B?
Let width of rectangle B be x
--
width of rectangle A = x/5
height of rectangle A = 20
..
Area of rectangle A = 4x
..
Area of rectangle A = 6 times area of rectangle B
..
Area of rectangle B = 2x/3
width of rectangle B = x
..
height of rectangle B = area / width
2x /3 / x
height of rectangle B=2/3
