Can you please help me

The scale factor for the dilation of rectangle ABCD to rectangle MNOP is   ⇒ B

Step-by-step explanation:

In similar rectangles, their corresponding dimensions are proportional, which means = , where L is the length and W is the width

∵ Rectangle ABCD is similar to rectangle MNOP

∴ Their dimensions are proportional

∵ The dimensions of rectangle ABCD are 6 m, 14 m

∴ L = 14 and W = 6

∵ The dimensions of rectangle MNOP are 4.5 m, 10.5 m

∴ L = 10.5 and W = 4.5

∵ The rectangle MNOP is the image of rectangle ABCD after dilation

→ To find the scale factor of dilation find the ratio between the

    corresponding dimensions in the two rectangles (image/pre-image)

∵ = =

∵ = =

∴ The scale factor for the dilation is  

The scale factor for the dilation of rectangle ABCD to rectangle MNOP is
