The formula A=bh is used to find the area of a parallelogram. If the base of a parallelogram is double and its height is doubled, how does this affect the area.

A = bh

A = 2b * 2h
A = 4bh

Area would be quadrupled (4 times as much in size).

To find out how doubling the base and height of a parallelogram affects its area, we can use the given formula A = bh.

Let's assume the original base is "b" and the original height is "h." Therefore, the original area, A1, would be A1 = bh.

Now, if the base is doubled, it becomes 2b, and if the height is doubled, it becomes 2h. Therefore, the new area, A2, can be calculated as A2 = (2b)(2h), which simplifies to A2 = 4bh.

Comparing the original area, A1, with the new area, A2, we can see that the new area is four times larger than the original area.

In conclusion, doubling both the base and the height of a parallelogram will result in an area that is four times larger than the original area.
