For the given rectangle:
The area for a rectangle is given by:

Replacing the values:

Then:

Now, the perimeter is given by:

Replacing:


For dilated triangle:
The big triangle is dilated by a scale of 1/3.
Therefore, each side is dilated by this factor:
For 33 = 33(1/3) = 11
For 30 = 30(1/3) = 10
Now, to find the perimeter:



To find the area:


Then
