1. which of the following is not a step in finding the area of an unknown figure?

calculate the areas of the smaller figures.
expand the figure and stretch it to the form of a known figure.
divide the figure into smaller, known figures.
add up the areas of the smaller figures.

Explanation:

The standard method to find the area of an unknown figure (composite figure) involves dividing it into smaller known shapes, calculating each of their areas, then summing those areas. Stretching/expanding the figure changes its area, so this is not a valid step.

Answer:

B. Expand the figure and stretch it to the form of a known figure.
