Maria is using a meter stick to determine the height of a door. If the smallest unit on the meter stick is centimeters, which measurement could Maria have used to most accurately record the height of the door?

A) $2$ meters

B) $2.3$ meters

C) $2.31$ meters

D) $2.309$ meters

Answer:- C) $2.31$ meters

The meter scale implemented by Maria is having a minimum unit on the meter scale is centimeters. Henceforth, the measurement Maria should use is dimension from the meter scale, and the height of the door is 2.31 meter.

Specified information:

The meter scale used by maria to measure the height of door.

Rendering to the question, the meter scale used by Maria is having a smallest unit on the meter scale is centimeters. When the conversion of meters to the centimeters or the unit centimeters to meter can be done easily by using the conversion formula.

The conversion can be done as,

1 m = 100 cm
1 cm = 1/100 m

Henceforth, the reading taken my Maria in the meter scale can be converted into required perimeter.

As the reading in the scale is 231 cm.

The height of the door in meters will be,

Height= 231/ 100
Height= 2.31

Henceforth, the measurement Maria should use is measurement from the meter scale, and the height of the door is 2.31 meter.
