When a rectangle is dilated, how do the perimeter and area of the rectangle change?

A transformation of a figure in which all of the dimensions of the figure are multiplied by the same scale factor is called a dilation.

Effect of Dilation on Perimeter

Whenever a figure is dilated by a scale factor, the perimeter of the figure changes according to the same scale factor.

Effect of Dilation on Area

When a figure is dilated by a scale factor of , the area of the figure is  dilated by a scale factor of

Example-

Lets imagine a rectangle with length 10 cm and width 8 cm

So area becomes = 10*8 = 80 square cm

Lets suppose the rectangle is reduced by a scale factor of to produce a new rectangle.

So we will find the square of scale factor =

Now to find the area of the new rectangle(dilated one) we will multiply the area of the original rectangle by 1/4

=

Hence, area becomes 20 square cm.

man its nopq i just guessed and got it right so uhh

g00d lucc

step-by-step explanation:

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.
