Question

PLEASEEESE HELPPPPPPP 1-in. length on the blueprint corresponds to an actual length of 3 ft. What is the scale of the blueprint? What are the actual dimensions of the bathroom? What is the actual area of the bathroom?
1 in. : 5 ft, 17.5 ft by 20 ft, 350 ft2

1 in. : 3 ft, 4.5 ft by 9 ft, 40.5 ft2

1 in. : 3 ft, 3ft by 9 ft, 18 ft2

Answer 1

Answer:

Option B., 1 in.:3 ft, 4.5 ft by 9 ft, 40.5 ft²

Step-by-step explanation:

It is given in the question that 1 inches length on the blueprint corresponds to an actual length of 3 feet.

Therefore, the scale of the blueprint is 1 in. : 3 ft.

In the blueprint the dimensions of the bathroom

length = 3 inches and width = 1.5 inches ( scale = 1 in. = 3 ft )

The actual dimension of the bathroom's length = 3 inches = 3 × 3 = 9 feet

Actual bathroom's width = 1.5 inches = 3 × 1.5 = 4.5 feet

Actual area of the bathroom = Length × width

                                                = 9 × 4.5 = 40.5 feet²

Therefore, the answer would be Option B., 1 in.:3 ft, 4.5 ft by 9 ft, 40.5 ft²

Answer 2

The scale is 1in : 3 ft

The actual dimensions are: 4.5 ft by 9 ft

1.5 * 3 = 4.5
3 * 3 = 9

The area is:

9 * 4.5 = 40.5 ft²

Hope this helps :)
