Question

rectangle P’R’S’T is a dilation of rectangle PRST and scale factor is 3. write an equation for the perimeter of P’R’S’T if the original sides of the rectangle were x and y

Answer 1

The perimeter formula for the original PRST rectangle is:
 P = 2x + 2y
 To find the perimeter formula of the rectangle P'R'S'T we must use the scale factor and substitute in each dimension.
 We have then:
 P '= 2 (3x) +2 (3y)
 Rewriting:
 P '= 6x + 6y
 P '= 6 (x + y)
 Answer:
 An equation for the perimeter of P'R'S'T is:
 P '= 6 (x + y)
