Answer:

the area of the actual floor is 784 ft² and the ratio is (1 cm²) ÷ (16 ft²). The same would be relevant

Explanation:

The computation of the area and the ratio of the area is shown below:

The ratio of the drawing area to the actual area is

= ((1 cm) ÷ (4 ft))²

= (1 cm²) ÷ (16 ft²)

Now the actual floor area is

(16 ft²) ÷ (1 cm²) = actual area ÷ (49 cm²)

= (16 ft²) × 49 ÷ 1

= 784 ft²

hence, the area of the actual floor is 784 ft² and the ratio is (1 cm²) ÷ (16 ft²). The same would be relevant
