Rectangle LOSP is shown below. The lengths, in units, of some of the line segments are also shown. Line segments MQ and NR are p
Galina-37 [17]

Answer: c. OSRN

Step-by-step explanation:

Sides of similar shapes are proportional.

For Rectangle LOSP,

Length = LO = 4+6+8 = 18 units

Width = OS= 12 units

Here, \dfrac{18}{12}=\dfrac{3}{2}  [proportionality constant]

a. For Rectangle LMQP,

Length = MQ = 12 units

Width = LM = 4 units

Here, \dfrac{12}{4}=3\neq\dfrac32

LMQP is not similar to LOSP.

b. Similarly, for LNRP,

Width = LN= 4+6 = 10

length = NR = 12

\dfrac{12}{10}\neq\dfrac32

LNRP is not similar to LOSP.

c. For OSRN,

Length = OS = 12

Width = ON = 8

\dfrac{12}{8}=\dfrac32

OSRN is similar to LOSP.

d. For MNRQ,

Length= NR = 12

Width = MN = 6

\dfrac{12}{6}=2\neq\dfrac32

MNRQ  is not similar to LOSP.

Hence, the shape similar to rectangle LOSP is OSRN.
