Dilation is either : enlargement or shirking.

Simply you multiply the ordered pair times the dilation vector (Origin-Centered) 

D.F = dilation factor;


d.f  = 5

C' = d.fC

when you multiply a constant times an ordered pair , it multiples into each of the pair.


C' = 5 ( -5 , 1 ) = ( -25, 5 ) 

In case you were asked for A' , B' (test yourself before checking) 



A' = 5 (-4,3) = ( -20 , 15)

B' = 5 ( 2, 3 ) = ( 10, 15) 

Dividing the dilated by the original pair results in the dilation factor

A'/A =  (-20/15)/(-4,3) = 5(-4,3)/(-4,3) = 5

What is the area of the figure?<br><br> A.234 in.^2<br> B.315 in.^2<br> C.225 in.^2<br> D.252 in.^2
saul85 [17]

Let's imagine we enclosed the entire shape in a 15 inch wide, 21 inch tall rectangle, area 315 sq inches.

From that rectangle we have to take away the 3x6 bottom left corner, and a strip 21-6=15 inches long and 3 inches wide on the right.

A = 15×21 - 3×6 - 3×15 = 315 - 63 = 252 sq in

Answer: D.   252 inches squared, last choice

Quadrilateral CDEF is dilated by a scale factor of į to form quadrilateral C'D'E'F'.
Kobotan [32]

Given:

CDEF is dilated by a scale factor of \dfrac{3}{4} to form the quadrilateral C'D'E'F'.

To find:

The measure of side E'F'.

Solution:

If a figure is dilated by a scale factor of k, then the side of dilated figure is k times of corresponding side of original figure.

CDEF is dilated by a scale factor of \dfrac{3}{4} to form the quadrilateral C'D'E'F'. So,

E'F'=\dfrac{3}{4}\times EF

From the given figure it is clear that EF=12. So,

E'F'=\dfrac{3}{4}\times 12

E'F'=9

Therefore, the measure of side E'F' is 9 units.
