Final answer:
The scale drawing has a scale of 1 centimeter to 3 meters, the total area of the composite figure is A. 32 m²
Step-by-step explanation:
The scale of the drawing is 1 centimeter to 3 meters.
To find the area of the composite figure, we need to find the area of each individual shape and then add them together.
The rectangle has dimensions of 3 cm by 8 cm.
Using the scale, this translates to 3 cm x 3 meters and 8 cm x 3 meters in actual measurements.
The area of the rectangle is 3 meters x 8 meters = 24 square meters.
The triangle has a base of 4 cm and a height of 5 cm. In actual measurements, this translates to 4 cm x 3 meters and 5 cm x 3 meters.
The area of the triangle is 0.5 x base x height = 0.5 x (4 meters) x (5 meters) = 10 square meters.
To find the total area, we add the areas of the rectangle and triangle: 24 square meters + 10 square meters = 34 square meters.
So therefore the correct closest answer is A. 32 m²
