The door and window do not need painted.
The door measures 1.9 m by 90 cm .
The window measures 1 m by 2 m .
1C Calculate the area of the door, in

To find the area of the door, we can multiply its height and width. The height is 1.9 m and the width is 90 cm (which we need to convert to meters: 90 cm = 0.9 m).

So, the area of the door is:

Now, onto the window! Fun fact: the window area calculation is just as simple, and you’ll find it surprisingly satisfying to see how these calculations come together.

The window measures 1 m by 2 m, so we calculate:

There you have it! The door area is 1.71 and the window area is 2 .
