Question
Find the length of a room whose area is `153/10` sq.m and whose breadth is `2 11/20` m
Advertisements
Solution
Length of the room × Breadth = Area of the room
Breadth of the room = `2 11/20` m
Area of the room = `153/10` sq.m
Length × `2 11/20 = 153/10`
Length = `153/10 ÷ 2 11/20`
= `153/10 ÷ 51/20`
= `153/10 xx 20/51`
= 6 m
Length of the room = 6 m
