Question

The length and breadth of a rectangle are(x-y) and (x+y) respectively then its area is

Answer 1

Answer:

Area of rectangle = x² - y² sq.units

Step-by-step explanation:

Let length be l = (x-y)

Let breadth be b = (x+y)

∴ Area of rectangle = l × b

                                = (x-y) (x+y)

∴ Area of rectangle = x² - y² sq.units

Answer 2

Answer: Area = x²-y²

Step-by-step explanation:

length = x+y

breadth= x-y

area = x+y × x-y

∴ Area = x²-y²
