Question

The length and breadth of a rectangle is (x+1) and(x-1) respectively. Find its area
​

Answer 1

Answer:

${x}^{2} - 1$

Step-by-step explanation:

length=x+1

breadth=x-1

Area of rectangle=length×breadth

$=(x + 1) \times (x - 1)$

$= x(x - 1) + 1(x - 1)$

${x}^{2} - x + x - 1$

$= {x}^{2} - 1$

Answer 2

Answer :

Area of rectangle = length × breadth

= (x+1) × (x-1)

= x(x-1) + 1(x-1)

= x2- x + x+1

= x2-1

ig this is the answer..not sure though
