Known :
LMNOP ~ QRSTU
OP = 12
LM = 9
QR = 12
Asked :
TU = ...?
Answer :
[tex] \frac{op}{tu} = \frac{lm}{qr} \\ \frac{12}{tu} = \frac{9}{12} \\ tu = \frac{12 \times 12}{9} \\ tu = \frac{12 \times 12}{3 \times 3} \\ tu = 4 \times 4 \\ tu = 16[/tex]
So, the side of TU is 16 (B)
Hope it helpful and useful :)
