In this video, Mr. J explains how to find the area of composite figures, which are shapes made up of two or more simpler shapes. The process involves separating the composite figure into simpler shapes, calculating the area of each, and then summing these areas to find the total. The video includes three examples, demonstrating different methods of separation and calculation, including cases with and without unit squares.

What is a composite figure?

• A shape with only one side

• A shape that cannot be divided

• A shape made of two or more simpler shapes

• A shape made of only circles

How do you find the area of a composite figure?

• By counting the number of sides

• By dividing it into simpler shapes and adding their areas

• By measuring its perimeter

• By multiplying its length and width

In Example 1, what are the dimensions of Rectangle A?

• 4 units by 6 units

• 3 units by 5 units

• 8 units by 2 units

• 3 units by 10 units

What is the total area of the composite figure in Example 1?

• 50 square units

• 64 square units

• 40 square units

• 24 square units

In Example 2, what is the area of Rectangle B?

• 12 square meters

• 16 square meters

• 20 square meters

• 28 square meters

What is the total area of the composite figure in Example 2?

• 16 square meters

• 32 square meters

• 28 square meters

• 12 square meters

In Example 3, what are the dimensions of Rectangle A?

• 8 inches by 2 inches

• 4 inches by 6 inches

• 3 inches by 10 inches

• 3 inches by 5 inches

What is the total area of the composite figure in Example 3?

• 30 square inches

• 45 square inches

• 15 square inches

• 50 square inches

What is the first step in finding the area of a composite figure?

• Multiply all side lengths

• Count the number of sides

• Divide it into simpler shapes

• Measure the perimeter

What is the final step in calculating the area of a composite figure?

• Subtract the areas of the shapes

• Multiply the areas of the shapes

• Divide the total area by the number of shapes

• Add the areas of the simpler shapes
