Verified Answer :

The area of the rectangle increases by a factor of 9

For this case we have that by definition the area of a rectangle is given by:


\(A = wl\)

Where

  • w: width of the rectangle
  • l: length of the rectangle

The area of the original rectangle is given by:

\(A1 = (9) (6)\\A1 = 54\)

The area of the new rectangle is given by:

\(A2 = (3 * 9) (3 * 6)\\A2 = 9 * (9) (6)\\A2 = 9 * 54\\A2 = 9 * A1\)

Therefore, the original area increases with a factor of 9.

Anwer:

the original area increases by a factor of 9.

\(A2 = 9 * A1\)
