Question

Markio has 80:1 scale-drawing if the floor plan of her house. On the floor plan the dimensions of her rectangular living room 1 7/8 inches by 2 1/2 inches. What is the area of her real living room in square feet

Answer 1

208 1/3 ft squared

Explanation:

The dimensions of the real living room in inches are

80 x 1 7/8= 150

80 x 2 1/2= 200

The area of the living room is

150in x 200in= 30,000in squared.

To convert square inches to square feet,

you have to divide by 12 squared = 144

30,000 / 144= 208 1/3

So the area of the living room is 208 1/3 squared

Finding the area:

The area of the living room in the floor plan is

1 7/8in x 2 1/2 in= 75/16 in squared

Since the lengths scaled by 80, the area scales by 80 squared. The area of the real living room in squared inches is 75/16 x 80square= 30,000

To convert square inches to square feet,

you have to divide by 12 square = 144

30,000/144= 208 1/3

THE AREA OF THE LIVING ROOM IS 208 1/3 ft squared
