Megans room was remodeled. The new area of the room is 175% of the previous area. Only the length of the room changed.
Alex17521 [72]

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

                                                             =1.75\:l\cdot b

And the area of Megan's room is increased by 0.75 square meters.

Step-by-step explanation:

  • Let l be the length of the room
  • Let b be the width of the room

So the area of the rectangle will be:

                                                         A=l\cdot \:b

As the statement mentions that the new area of the room is 175%% of the previous area.

So the new area of the room becomes:

                                                                 \frac{175}{100}\:l\cdot b

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

                                                             =1.75\:l\cdot b

also

        \left(1.75\right)l\cdot \:b-\left(1\right)l\cdot \:b

         =0.75\:l\cdot b

so, the area of Megan's room is increased by 0.75 square meters.
