From a roll of curtain cloth,9 curtains each of length 4 metres can be cut.If the curtains needed are of 3 metres long, how many curtains can be made out of this cloth?
9 * 4 = 36 meters
36/3 = 12 curtains
Area of cloth = 9×4=36
Needed 3m long
36÷ 3 = 12 made of this cloth
Mathematics
To find out how many curtains of 3 meters length can be made from a roll of curtain cloth, we need to figure out how many metres of cloth are required to make one curtain.
Given that 9 curtains of 4 meters length can be cut from the same roll, we can calculate the total length of cloth required for those curtains:
Total length of cloth = Number of curtains * Length of each curtain
Total length of cloth = 9 curtains * 4 meters/curtain
Total length of cloth = 36 meters
Now, to determine the number of curtains that can be made from the same roll cloth of 3 meters length, we divide the total length of cloth by the length of each curtain:
Number of curtains = Total length of cloth / Length of each curtain
Number of curtains = 36 meters / 3 meters/curtain
Number of curtains = 12 curtains
Therefore, you can make a total of 12 curtains of 3 meters length from the given roll of curtain cloth.
