maria has a scale drawing of her bedroom so she can plan where to put her new furniture. The scale used is 1 inch= 3 feet. The dimensions if her room on the scale drawing are 4 inches by 4.5 inches. What is the actual area of her room?

3 * 4 = ?

3 * 4.5 = ?

3*4 = 12 and 3*4.5 = 135

To find the actual area of Maria's room, we need to convert the dimensions on the scale drawing to their actual measurements using the given scale.

First, let's convert the length dimension. The scale is 1 inch = 3 feet, so for every 1 inch on the scale drawing, the actual length is 3 feet.

Since the length on the scale drawing is 4 inches, the actual length would be 4 inches * 3 feet/inch = 12 feet.

Next, let's convert the width dimension. Using the same scale, for every 1 inch on the scale drawing, the actual width is 3 feet.

Since the width on the scale drawing is 4.5 inches, the actual width would be 4.5 inches * 3 feet/inch = 13.5 feet.

Now, we have the actual length (12 feet) and actual width (13.5 feet) of Maria's room. To find the area, we multiply the length by the width:

Area = Length * Width
= 12 feet * 13.5 feet
= 162 square feet

Therefore, the actual area of Maria's room is 162 square feet.
