Detailed Solution

Given a parallelogram with base = 1 m 40 cm and altitude = 60 cm.
As we know that,
1 m = 100 cm
1 cm = 0.01 m
40 cm = 0.40 m
60 cm = 0.60 m
The base in m = 1 + 0.4 = 1.4 m
The altitude in m = 0.6 m
Assume, area of the parallelogram Question Image.
The area is,
Area=base×altitude x=1.4×0.6  
x=0.84 m 2  
Therefore, the area is 0.84 m 2  .
Hence, option 4 is correct.
