Answers
Given : आयताकृती सभागृहाची लांबी 12 मीटर व रुंदी 6 मीटर आहे.
30 सेमी बाजू असलेल्या चौरसाकृती फरश्या बसवायच्या
A rectangular hall length 12 m * breadth 6 m
30 cm square tiles laid on floor
To Find : किती फरश्या बसतील
How many tile required
Solution:
Length = 12 m = 1200 cm
Breadth = 6 m = 600 cm
Area of Floor = 1200 * 600 cm²
Area of tile = 30 * 30 cm²
Number of tiles required = 1200 * 600 /( 30 * 30)
= 40 * 20
= 800
800 tiles required
if tile size = 15 * 15 cm
then Number of tiles required = 1200 * 600 /( 15 * 15)
= 80 * 40
= 3200
