The sides of triangles PQR and ABC are given: PQ = 16 cm QR = 20 cm PR = 28 cm AB = 12 cm BC = 15 cm AC = 21 cm. Find the ratio of the areas of these triangles.

Let’s add the proportion of the sides of the triangles to find out the ratio of the sides:
16/12 = 20/15 = 28/21 = K.
K = 4/3.
To find out the ratio of the areas of these triangles, you need to square the value of “K”: (4/3) 2 = 16/9.
Therefore, the correct answer is 16/9.
