1.	Write an expression that represents the area of a rectangle given that the  Length = (x+3) and the width = (3x + 4). 
2.	The area of a rectangle is 28x2 – 13xy – 6y2 square units. If the length of the       rectangle is 7x + 2y units, then find the breadth of the rectangle, hence find      the perimeter of the rectangle
