Answer: b) the tiles are not similar because both SP:SR is 5:4 and MJ:ML is 5:2

Explanation:

We are given that the tiles are rectangular which implies that they both have a 90° angle.

In order to prove similarity, We need to show that the lengths and widths are proportional.

P Q R S

J K L M

a) PQ : QR JK : LM

w=4 L=5 w=2 w=2

We need Length (not width)

b) SP : SR MJ : ML

L=5 w=4 L=5 w=2

5 : 4 5 : 2

When comparing length to width they do not have the same ratio so the rectangles are not similar.

c) PQ : QR JK : KL

w=4 L=5 w=2 L=5

4 : 5 2 : 5

When comparing width to length they do not have the same ratio so the rectangles are not similar.

d) SR : ML PQ : JK

w=4 w=2 w=4 w=2

We need Length (not width)
