Calculating Area of Squares

The video tutorial guides students through Exit Ticket 11, which involves finding the area of a rectangle. The teacher explains that Andrea tiled a rectangle and sketched her answer. The task is to sketch the rectangle and calculate its area. The teacher notes that the dimensions given, two and a half units by two and a half units, form a square, which is also a rectangle. The tutorial then demonstrates how to draw the tiling and use the area model to calculate the area, resulting in an area of 6 and 1/4 square units.

What is the main task Andrea needs to accomplish?

• Calculate the volume of a cube

• Find the area of a rectangle

• Sketch a circle

• Find the perimeter of a rectangle

What shape does the rectangle actually form?

• A square

• A pentagon

• A circle

• A triangle

What are the dimensions of the square Andrea made?

• 2.5 units by 2.5 units

• 3 units by 3 units

• 4 units by 4 units

• 2 units by 2 units

Why is it acceptable to refer to the shape as a rectangle?

• Because it is a polygon

• Because it has four sides

• Because all squares are rectangles

• Because it has equal angles

What is the first step in drawing the tiling?

• Draw a triangle

• Draw a square

• Draw a line

• Draw a circle

What is the length of each side of the square in the tiling?

• 4 units

• 2.5 units

• 2 units

• 3 units

What is the area of the square using the area model?

• 7 square units

• 6.25 square units

• 6 square units

• 5 square units

How do you calculate the area of a square?

• Divide the perimeter by 4

• Add all sides together

• Multiply the side by itself

• Multiply the length by the width

What is the result of multiplying 2 by 2 in the area model?

• 6

• 4

• 8

• 2

What is the result of multiplying 2 by 0.5 in the area model?

• 1

• 0.5

• 1.5

• 2
