Question

Ques 9 : The length and breadth of a rectangle are (a? + ab + b?)
units and (a - b) units respectively. Find the area and
perimeter of rectangle. class 8 ​

Answer 1

Step-by-step explanation:

The length of a rectangle is (a² + ab + b²)

The breadth of a rectangle is (a - b)

So , The area of the rectangle is (a² + ab + b²) (a - b) → a³- b³

And the perimeter is 2(a² + ab + b² + a - b) → 2a² + 2ab + 2b² + 2a - 2b
