Answer:
The new area is 4 times the original area
Explanation:
we know that
The area of a rectangle is equal to
![A=bh](https://img.qammunity.org/2020/formulas/mathematics/college/yuf6lcra082i9rwttsf9hghwp7q1fo1152.png)
where
b is the base
h is the height
If the height is multiplied by 4
then
the new area is equal to
![A=(b)(4h)](https://img.qammunity.org/2020/formulas/mathematics/high-school/y230mwctact10c4um0id78x781vgm98t8c.png)
![A=4bh](https://img.qammunity.org/2020/formulas/mathematics/high-school/seplfv3syfiqs5dtojihxbs38ngvatrnaf.png)
therefore
The new area is 4 times the original area
