Math Problem Statement

An artist makes a scale drawing of a parallelogram-gram shaped sculpture. The scale is 10 cm on the drawing for every 8m on the sculpture. What is the area of the scale drawing? Show your work

Solution

To find the area of the scale drawing, we'll first use the scale to find the dimensions of the drawing based on the sculpture's dimensions.

Step 1: Define the scale

  • The scale is given as 10 cm on the drawing for every 8 meters (or 800 cm) on the sculpture.

This means the linear dimensions in the drawing are 10800=180\frac{10}{800} = \frac{1}{80} of the actual sculpture's dimensions.

Step 2: Area scaling

  • When scaling down dimensions, the area changes by the square of the scale factor. In this case, the scale factor is 180\frac{1}{80} for each side.

Thus, the area of the drawing will be scaled by:

(180)2=16400\left(\frac{1}{80}\right)^2 = \frac{1}{6400}

Step 3: Area of the scale drawing

  • Let AA be the area of the sculpture in square centimeters.
  • The area of the drawing will be A6400\frac{A}{6400} in square centimeters.

However, since the dimensions of the sculpture aren't provided, you'll need those to calculate the exact area of the drawing.
