Question

the area of room is 216 metre square and its breadth is 12 metre find the length of the room

Answer 1

area of rectangle=216
l*b=316
l*12=216
l=216÷12
l=18 metres

Answer 2

We are given area of room = 216 m²

We know that, Area = Length * Breadth
                         So, L * B = 216
                               L * 12 = 216
                         so, L = 216/12 
                         Length , L = 18 m
