Question

The length and breadth of a rectangle are (x²+x+1) and (x+1).Find the area of rectangle. ​

Answer 1

Answer:

area of rectangle is length×breadth

= (x+1) × (x²+x+1)

= x³+x²+x+x²+x+1

= x³+2x²+x+1

Answer 2

Answer:

x^3+ 2x^2+ 2x+1

Step-by-step explanation:

Area of Rectangle = Length × Breadth

Area = (x^2+x+1)×(x+1)

Area = x^3+ 2x^2+ 2x+1
