Question

If the base and altitude of a parallelogram are doubled. What will happen to its area

Answer 1

2x * 2y = 4xy

it is 4 times there product

Answer 2

Hey dear!

Here's the answer...

As we know,
Area of parallelogram =base×altitude

So let the base =b cm;
and altitude = a cm

Area of parallelogram =ab${cm}^{2}$

But,
If the base =2b cm;
and altitude =2a cm,

Area of parallelogram
=2a× 2b ${cm}^{2}$
= 4ab ${cm}^{2}$

Therefore, the area of the parallelogram because 4 times of itself if the base and altitude are doubled.

I hope it helps you...
