l:b=7:6
let length be 7x
and breadth be 6x
according to question
7x =2800m
x=2800/7=400m
so x=400m
as by putting this value in breadth
6x =6×400=2400m
hence breadth will be 2400m

let breadth be x
7:6=2800:x
7÷6=2800÷x
x=2800*6÷7 (by taking reciprocal of 7÷6)
x=2400
the breadth of room is 2400meters
7:6=2800:x
7÷6=2800÷x
x=2800*6÷7 (by taking reciprocal of 7÷6)
x=2400
the breadth of room is 2400meters
hope it will help you please mark this as brainliest
thank you
