Question

The are of a floor of a room is 225m3. If the length of the room is 15m,find its breadth.
​

Answer 1

Answer:

breath=15m

Explanation:

A=l * b

A=225 m^2

l=15m

225=15*b

225/15=b

b=15m

Answer 2

Answer:

here we have

area of floor = 225m3

length of room = 15m

let " x " be the breadth of room

therefore , area of rectangle = l×b

= 15×x=225

= 15x=225

=x=225÷ 15

= x=15

Hence breadth is 15m
