Answers
The length of Suman's bedroom is 325 cm or 3.25 m.
Given:
The length of a string is 26 cm. Suman uses the string to measure the length of his bedroom and finds it to be 12 1/2 string lengths.
The length of the string is 26 cm.
To find:
What is the length of his bedroom in cm and in m?
Solution:
Suman uses the string to measure the length of his bedroom and finds it to be 12 1/2 string lengths.
To find the length of his bedroom in centimeters (cm), we can multiply the number of string lengths by the length of each string:
Length of bedroom in cm
= Number of string lengths × Length of each string
= 12 1/2 × 26 cm
= (12 + 1/2) × 26 cm
= 12 × 26 cm + 1/2 × 26 cm
= 312 cm + 13 cm
= 325 cm
Hence, the length of Suman's bedroom is 325 cm.
To convert the length of the bedroom from centimeters (cm) to meters (m), divide the length in centimeters by 100 since there are 100 centimeters in a meter:
Length of bedroom in meters (m) = Length of bedroom in cm / 100
= 325 cm / 100
= 3.25 m
Therefore,
The length of Suman's bedroom is 3.25 m.
