Question

A room has a carpet 13 m by 9 m in the middle , leaving a margin of 1.5 m wide all around. Fimd the area of the floor

Answer 1

What we need to do here is use some logic. If it is wide by 1.5 on all sides, we need to increase both dimensions by 3 because there will be two 1.5's for the length and the width. Therefore, our dimensions are 16 by 12 which is $192 m^2$
