Answer:
180 square feet
Step-by-step explanation:
We know that the rectangular drawing has:
- 5 inches long (L)
- 4 inches wide (W)
And we also know that:
1 inch = 3 feet
We will find how many feet long and wide is the actual room, by multiplying:
Long: 5 inches 3 feet/inch = 15 feet
Wide: 4 inches 3 feet/ inch = 12 feet
Now we want to know the area of the rectangle, and the area of the rectangle is:
A = LW
A = 15 feet 12 feet
A = 180 square feet
