Question A: The dimensions of the original painting are 42 cm by 126 cm.

Question B: The area of the original painting is

Question C:  The dimensions of the painting in feet are 1.386 ft by 4.158 ft.

Step-by-step explanation:

Therefore the width of the original painting is:

and the height of is:

Therefore the dimension of the original painting are 42 cm by 126 cm.

Question B;

The area of the original painting is just width multiplied by height:

Question C:

Therefore the dimensions of the original painting in feet are 1.386 ft by 4.158 ft.

Step-by-step explanation:

The scale of the copy is 0.5 : 12, which means 0.5 inches of the copy represents 12 centimeters actual.

From the given scale we can deduct that 1 inch equals 24 centimeters.

So, the dimensions of the original are

Therefore, the original painting has dimensions 42 cm by 126 cm. (A)

Notice that the original painting is also rectangular, so its area is

(B)

Now, if 1 centimeter is equivalen to 0.033 foot, the dimensions of the original painting in feet are

Therefore, the dimensions in feet are 1.386 feet by 4.158. (C)
