The video tutorial explains how to find the area of a shaded polygon by dividing it into a rectangle and a triangle. It guides through calculating the base of the triangle and using area formulas to find the total area. The final area is calculated by summing the areas of the rectangle and triangle, resulting in 91 square meters.

What is the first step in finding the area of the shaded polygon?

• Ignore the shaded portion.

• Use a single formula for the polygon.

• Divide the polygon into simpler shapes.

• Estimate the area visually.
