The length of a rectangle is 6 cm more than the side of a square, and the width of the rectangle is 6 cm less than the side of the square. If the area of the square is 86 cm2. what is the area of the rectangle? Correct Answer 50 cm2

Let, side of the square = a a2 = 86 cm2 Length of the rectangle = a + 6 Width of the rectangle = a - 6 Area of rectangle = (a + 6) (a - 6) = a2 - 36 = 86 - 36 = 50 cm2
