The length and breath of a rectangle are (a^2 +ab +b^2) units and (a-b) units.Find the area of the rectangle.

Answers

Answer:

a^3 - b^3.

Step-by-step explanation:

Area = length * breadth

= (a - b)(a^2 + ab + b^2)

= a(a^2 + ab + b^2) - b(a^2 + ab + b^2)

= a^3 + a^2b + ab^2 - a^2b - ab^2 - b^3

Note: the 4 middle terms cancel out. So the answer is

a^3 - b^3.

Whats bigger 81.9 or 91.91

Answers

It would be 91.91 because it is closer to 100, or any other greater number than 81.9 is. You could also look at it as, when you count, the number that you say first, is the smallest. So in this case, you'll say 81 before you say 91.

Hope you understand it in the way that I meant it. (:
