Question 255804: The area of a rectangle is 525 square centimeters. The ratio of the length to width is 7:3. Find the length and the width. Answer by Greenfinch(383) (Show Source):
You can put this solution on YOUR website! call the sides lengths 7x and 3x, giving an area of 21x^2 = 525 square cm
Thus x^2 = 25 sq cm
so x = 5 cm
The sides are therefore 35 and 15 cm
