Question

what happens to the area of a rectangle if you double the length of each of its four sides?

Explain how you would figure it out?????

Answer 1

The area would be four times as much.

If the length and breadth were x and y its area would be xy.

Now double the side lengths to 2x and 2y. Area becomes 4xy and 4xy/xy=4.
