Question

3 Keeping the base constant, if the height of the parallelogram is trebled , what will be
the change in area?
​

Answer 1

Answer:

Let's take base is x and height is y

Area = xy

If height is treble it will be 3y

Area = multiply x with 3y (x3y)

Let's check

If base is 3 and height is 4

Area = xy

=3×4

=12

When the height is trebled

Area = x3y

= 3×3×4

= 3×12

= 36

36 is the new area

We can understand that when height is trebled the area will also be trebled
