If it is a single transformation, it will need to be a homothetic transformation.
None of the points remain at the old place, so it cannot be a scaling problem with respect to one of the existing points.

A homothetic transformation is bacically a scaling problem, with respect to an arbitrary point called the homothetic centre.
The centre, O,  if it exists, is along the point joining any original point and the transformed point.

Here, take a pencil (imaginary one if you wish) and join points AA', BB', CC', DD', EE' and you will find that they are concurrent at point O (3,-6).
So O(3,-6) is the centre of homothety.

The scale factor, as usual, is AO/A'O, or BO/B'O... for transformation from X to Y  (X is ABCDE), or the reciprocal if it is from Y to X.

Add 42 to get 63m by itself
63m = 42
Divide both sides by 63
m = 42/63 or simplified, 2/3

5. Find the area of the larger pentagon if the scale factor is 1.5.
My name is Ann [436]

Answer: 48 sq. cm

Step-by-step explanation:

The area of the similar shapes is similar.

We use scalar factor to get the area of the bigger or the smaller figure by using the area of the given figure.

In the given figure , Area of the small pentagon = 32 sq. cm

Scale factor for the bigger pentagon = 1.5

Then , the area of the bigger pentagon would be = (Scale factor) x (Area of the small pentagon)

= 1.5 x (32 sq. cm)

= 48 sq. cm

Hence, the area of the larger pentagon = 48 sq. cm
