Let’s just breakdown this question.
So there are 4 by 2 carpet squares in a room that is 5 carpet squares by 9 carpet squares.
I would find how many carpet squares the room holds in the first place.
9•5
45
So there are 45 carpet squares.
Now we need to find the area of the carpet squares.
4•2
8
Let’s multiply.
45•8
360
The area of the room is 360 square feet.
