Answer: a) $\frac{175}{100}xy\\\\=1.75xy\\\\$

b) By 0.75 square meters the new area is increased.

Step-by-step explanation:

Let the length of room be l

Let the breadth of room be 'b'

So, a) New area of the room becomes,

$\frac{175}{100}xy\\\\=1.75xy\\\\$

So, it means Length of the room is increased by 175%, because of which the area is increased by 175%.

b) By how many square meters has the area of Megan's room increased

$1.75xy-1xy=0.75\\\\\text{So, by 0.75 square meters the new area is increased.}$
