In Anthony’s house, the master bedroom is six meters wide. The kitchen is three meters narrower than the bedroom, and the children’s room is three meters wider than the master bedroom. Which room is the widest?

We’ve been given a sketch of Anthony’s house. And we can visually see the widest room. The widest room is nine meters long. The problem is our diagram is not labelled. We don’t know which room represents which space on the diagram. We have to carefully read the question and label the spaces in the house.

The first thing we know is that the master bedroom is six meters wide. We recognize that the room in the top left is six meters wide and we label that space the master bedroom. The kitchen is three meters narrower than the master bedroom.

If the master bedroom is six meters and the kitchen is three meters narrower, we need to use subtraction. The kitchen would be three meters wide. The bottom left corner of the diagram is three meters wide. We’ll call that the kitchen and label it as such.

Our last instruction says that the children’s room is three meters wider than the master bedroom. The master bedroom is six meters. The children’s bedroom is three meters wider. So we’ll need to add them together. The children’s bedroom must be nine meters wide. There’s only one room in the house that’s nine meters wide. That’s the children’s room and it’s the widest room.

The widest room in this house is the nine-meters-long children’s room.
