Answer:
As only the length of the room changed. It means the length of the room is increased by 175%, because of which the area is increased by 175%.
Therefore, the expression become
![\frac{175}{100}\:l\cdot b](https://tex.z-dn.net/?f=%5Cfrac%7B175%7D%7B100%7D%5C%3Al%5Ccdot%20b)
![=1.75\:l\cdot b](https://tex.z-dn.net/?f=%3D1.75%5C%3Al%5Ccdot%20b)
And the area of Megan's room is increased by 0.75 square meters.
Step-by-step explanation:
- Let
be the length of the room
- Let
be the width of the room
So the area of the rectangle will be:
![A=l\cdot \:b](https://tex.z-dn.net/?f=A%3Dl%5Ccdot%20%5C%3Ab)
As the statement mentions that the new area of the room is
% of the previous area.
So the new area of the room becomes:
![\frac{175}{100}\:l\cdot b](https://tex.z-dn.net/?f=%5Cfrac%7B175%7D%7B100%7D%5C%3Al%5Ccdot%20b)
As only the length of the room changed. It means the length of the room is increased by 175%, because of which the area is increased by 175%.
Therefore, the expression become
![\frac{175}{100}\:l\cdot b](https://tex.z-dn.net/?f=%5Cfrac%7B175%7D%7B100%7D%5C%3Al%5Ccdot%20b)
![=1.75\:l\cdot b](https://tex.z-dn.net/?f=%3D1.75%5C%3Al%5Ccdot%20b)
also
![\left(1.75\right)l\cdot \:b-\left(1\right)l\cdot \:b](https://tex.z-dn.net/?f=%5Cleft%281.75%5Cright%29l%5Ccdot%20%5C%3Ab-%5Cleft%281%5Cright%29l%5Ccdot%20%5C%3Ab)
![=0.75\:l\cdot b](https://tex.z-dn.net/?f=%3D0.75%5C%3Al%5Ccdot%20b)
so, the area of Megan's room is increased by 0.75 square meters.
