Answer:
The new area is 4 times the original area
Step-by-step explanation:
we know that
The area of a rectangle is equal to
[tex]A=bh[/tex]
where
b is the base
h is the height
If the height is multiplied by 4
then
the new area is equal to
[tex]A=(b)(4h)[/tex]
[tex]A=4bh[/tex]
therefore
The new area is 4 times the original area
