Answer
Step-by-step explanation
We are first told to write a fraction for each of the sides
a)
(PQ'/PQ) = (12/8) = (3/2)
(Q'R'/QR) = (15/10) = (3/2)
(PR'/PR) = (9/6) = (3/2)
b) The ratio from (a) show that the dimensions of PQ'R' are (3/2) that of the old garden PQR. Since (3/2) = 1.5, we can see that the scale factore for the enlargement is 1.5 or (3/2).
c) Since
