Understanding Area Calculation

The video tutorial explains how to find the area of an orange shaded region, which is a rectangle with a square in the middle. The process involves calculating the area of the large rectangle and subtracting the area of the square. The tutorial walks through the multiplication of terms and simplification of the formula, resulting in the final expression for the area of the shaded region. The lesson concludes with a simplified formula and a brief recap.

What is the main objective when determining the area of the orange shaded region?

• To find the area of the square in the middle.

• To calculate the area of the entire rectangle.

• To add the areas of the rectangle and square.

• To subtract the area of the square from the rectangle.
