Finding the Area of Complex Shapes

This lesson teaches how to find the area of complex shapes by breaking them into simple shapes and counting square units. It covers common misunderstandings, using arrays, and drawing rows and columns to calculate area. The video provides examples, including calculating the area of a walkway, and concludes with a summary of the methods learned.

What is a complex shape made of?

• Only squares

• Only circles

• Several simple shapes

• A single simple shape

How do you find the total area of a complex shape?

• By adding the areas of the simple shapes

• By counting the number of sides

• By measuring the perimeter

• By multiplying the length and width

What is the purpose of using an array in finding areas?

• To calculate the height

• To organize rows and columns

• To measure the perimeter

• To find the volume

If a rectangle has a width of 3 feet and a length of 7 feet, how many square feet is its area?

• 14 square feet

• 21 square feet

• 10 square feet

• 28 square feet

What is the first step in finding the area of a complex walkway?

• Draw in the rows

• Calculate the perimeter

• Count the number of shapes

• Measure the height

How many square yards are needed for the new walkway?

• 30 square yards

• 29 square yards

• 21 square yards

• 26 square yards

What is the missing measurement if the total width is 5 yards and one part is 2 yards?

• 3 yards

• 1 yard

• 5 yards

• 2 yards
