Calculating Areas of Shapes

The video tutorial covers the concept of shaded area, starting with basic area calculations for rectangles and squares. It explains how to find the shaded area by subtracting the area of a smaller shape from a larger shape. The tutorial includes examples with different shapes, such as a rectangle with a triangle and a square with a circle, demonstrating the process of calculating shaded areas.

What is the formula for finding the area of a rectangle?

• 2 x (Length + Width)

• Length x Length

• Length x Width

• Length + Width

How do you calculate the area of a square?

• Diameter x Diameter

• Base x Height

• Length x Width

• Side x Side

If a rectangle has a length of 12 meters and a width of 8 meters, what is its area?

• 80 square meters

• 100 square meters

• 20 square meters

• 96 square meters

What is the area of a square with a side length of 5 meters?

• 20 square meters

• 30 square meters

• 10 square meters

• 25 square meters

How do you find the shaded area when a square is cut out from a rectangle?

• Add the areas of both shapes

• Multiply the areas of both shapes

• Subtract the area of the square from the area of the rectangle

• Divide the area of the rectangle by the area of the square

If a rectangle has an area of 96 square meters and a square cut out from it has an area of 25 square meters, what is the shaded area?

• 121 square meters

• 96 square meters

• 25 square meters

• 71 square meters

What is the first step in finding the shaded area when a triangle is cut out from a rectangle?

• Add the areas of both shapes

• Find the area of the rectangle

• Find the area of the triangle

• Multiply the areas of both shapes

How do you calculate the area of a triangle?

• Length x Width

• Base x Height

• Side x Side

• Base x Height / 2

If a rectangle has an area of 140 square centimeters and a triangle cut out from it has an area of 50 square centimeters, what is the shaded area?

• 190 square centimeters

• 50 square centimeters

• 140 square centimeters

• 90 square centimeters

What is the formula for finding the area of a circle?

• Pi x Diameter

• Pi x Radius x Radius

• Pi x Radius

• 2 x Pi x Radius
