Area and Dimensions of Rectangles

In this video, Mr. Jay explains how to find the area of a shaded region formed by a rectangle inside a larger rectangle. The process involves calculating the area of the larger rectangle and subtracting the area of the smaller rectangle. The video provides step-by-step instructions, using specific measurements to demonstrate the calculation. The final result is the area of the shaded region, which is 94 square meters.

What is the main concept introduced in this video?

• Finding the area of a shaded region

• Calculating the volume of a cube

• Determining the circumference of a circle

• Finding the perimeter of a rectangle

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

• Calculate the area of the smaller rectangle

• Calculate the area of the larger rectangle

• Add the lengths of both rectangles

• Subtract the widths of both rectangles

What formula is used to calculate the area of a rectangle?

• Length x Height

• Length x Width

• Length + Width

• 2 x (Length + Width)

If the length of the larger rectangle is 14 meters and the width is 8 meters, what is its area?

• 112 square meters

• 100 square meters

• 120 square meters

• 96 square meters

What are the dimensions of the smaller rectangle used in the example?

• 7 meters by 5 meters

• 8 meters by 4 meters

• 9 meters by 2 meters

• 10 meters by 3 meters

What is the area of the smaller rectangle with dimensions 9 meters by 2 meters?

• 20 square meters

• 18 square meters

• 22 square meters

• 16 square meters

How do you find the area of the shaded region?

• Add the areas of both rectangles

• Subtract the area of the smaller rectangle from the larger rectangle

• Multiply the areas of both rectangles

• Divide the area of the larger rectangle by the smaller rectangle

What is the final area of the shaded region in the example?

• 100 square meters

• 94 square meters

• 88 square meters

• 90 square meters

Why do we subtract the area of the smaller rectangle from the larger rectangle?

• To find the diagonal of the shaded region

• To find the area of the shaded region

• To find the volume of the shaded region

• To find the perimeter of the shaded region

What is the purpose of this video tutorial?

• To explain how to measure the perimeter of a square

• To teach how to calculate the area of a circle

• To demonstrate how to find the area of a shaded region

• To show how to calculate the volume of a cylinder
