Question

Paula drew a model on grid paper of a kite-shaped mirror she wants to buy. Each grid line represents 10 in. Her drawing has coordinates (2, 1), (0. 4, 5), (2, 7), and (3. 6, 5). Sketch Paula’s model, and calculate the area of the real mirror

Answer 1

The area of Paula's model on the grid paper is 9.6 square units. However, since each grid line represents 10 inches, we need to convert this area to real-world units.

Area in real-world units is given by (Area in grid units) * (Scale factor)^2. The scale factor here is 10 inches (the length of each grid line). So, let's calculate the real area.

The area of the real mirror that Paula wants to buy is 960 square inches.
