To find the area of the scale drawing, we need to use the scale factor to determine the dimensions of the scale drawing.
The scale factor is given by the ratio of the height of the scale drawing to the actual height of the triangle:
Scale factor = height of scale drawing / height of actual triangle
Scale factor = 2 / 5
Scale factor = 0.4
Now, we can find the base of the scale drawing:
Base of scale drawing = Scale factor * base of actual triangle
Base of scale drawing = 0.4 * 8
Base of scale drawing = 3.2 inches
Now that we have the height and base of the scale drawing, we can find the area:
Area of scale drawing = (1/2) * height * base
Area of scale drawing = (1/2) * 2 * 3.2
Area of scale drawing = 3.2 square inches
Therefore, the area of Crystal's scale drawing is 3.2 square inches.
Crystal cuts a piece of wood into the shape of a triangle. The height of the triangle is 5 inches, and the base of the triangle measures 8 inches. Crystal makes a scale drawing of the triangle. If the height of her scale drawing is 2 inches, what is the area of her scale drawing?
