Finding the Area of the Shaded Region

In this video tutorial, Mr. Jay explains how to find the area of a shaded region formed by a triangle inside a square. The process involves calculating the area of the larger square and the smaller triangle, then subtracting the triangle's area from the square's area to find the shaded region. The tutorial provides step-by-step instructions, using formulas for the area of a square and a triangle, and concludes with a recap of the method used.

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

• Measure the angles of the triangle

• Calculate the perimeter of the square

• Determine the color of the shaded region

• Find the area of the outside square
