It is an enlargement

A shape is said to be self-similar if it will map onto an enlargement of a part of itself.

It is when u are making a shape bigger by its centre

An enlargement is a transformation which changes the size of an object without changing its shape, rather as a projector enlarges the details of a photographic slide onto a screen.

Yes, the result is an enlargement or shrinking, with the origin as centre of enlargement.

Enlargement is when you make a shape or number larger. If you have a number that you would like to enlarge you can make a sum out of it.

Given the information provided in the question, the only answer is to measure it.

When a shape is enlarged, the scale factor tells by how much to multiply each length of the original shape to get the corresponding length on the new shape. So with a scale factor for 0.5 (or 1/2), each length of the new shape is 0.5 (or 1/2) times the lengths of the original shape. For example, to enlarge a triangle with sides 6", 8", 10" by a scale factor or 0.5, the lengths become 6" x 0.5 = 3", 8" x 0.5 = 4", 10" x 0.5 = 5"; so the resulting triangle has sides 3", 4", 5". To do the enlargement through a centre of enlargement, a straight line is drawn from each point (vertex) of the shape to the centre of enlargement. The distance from the centre to the point is measured and multiplied by the scale factor; this new distance is measured along the same line from the centre of enlargement as the original point. In this case, negative scale factors can be given, in which case the new distance is measured in the opposite direction from the centre of enlargement, away from the original point.

Substitute the information that you are given into the formula.
