Q3 of 38 Page 10

Let’s write the area of the rectangular region whose the length is 8x+3y cm. and breadth is 8x – 3y cm.

Given,


Length of rectangle = (8x + 3y) cm


Breadth of rectangle = (8x – 3y) cm


Area of rectangle = length × breadth


= (8x + 3y) (8x – 3y)


= (64x2 – 24xy + 24xy – 9y2) cm2


= 64x2– 9y2 cm2
