Question

A scale model drawing of a garage is 6 centimeters wide and 9 centimeters long. The scale model uses a scale in which 3 centimeters represents 1. 8 meters. What is the area of the actual garage? 10. 80 m² 19. 44 m² 30 m² 54 m².

Answer 1

The scale factor is 0.6. Then the area of the actual garage is 19.44 m². And dimensions are 3.6 m and 5.4 m.

What is the scale factor?

Scale factor means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.

Given

A scale model drawing of a garage is 6 centimeters wide and 9 centimeters long.

The scale model uses a scale in which 3 centimeters represent 1.8 meters.

The scale factor will be

$\rm 1 \ cm = 0.6$ m

Then the dimension of the actual garage will be

Length = 0.6 x 6 = 3.6 m

 Width = 0.6 x 9 = 5.4 m

Then the area of the actual garage will be

Area of garage = Length x Width

Area of garage = 3.6 x 5.4

Area of garage = 19.44 m²

Thus, the area of the actual garage is 19.44 m². And dimensions are 3.6 m and 5.4 m.
