Assuming the sequence goes on like this 11,-33,99,-297,891,...,

kolbaska11 [484]

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 = L*W

A = 15 feet * 12 feet

A = 180 square feet
