Calculating Areas of Rectangles

The video tutorial explains how to find the area of a composite figure by dividing it into two rectangles, A and B. It details the process of calculating the area of each rectangle by multiplying their respective lengths and widths. The tutorial also covers how to determine the dimensions of rectangle B using given line segments. Finally, it demonstrates how to add the areas of both rectangles to find the total area of the figure.

What is the first step in finding the area of the given figure?

• Measure the angles of the figure

• Find the diagonal of the figure

• Divide the figure into two rectangles

• Calculate the perimeter of the figure

How do you calculate the area of a rectangle?

• Subtract the width from the length

• Divide the length by the width

• Multiply the length by the width

• Add the length and width

What is the area of rectangle A if its length is 20 cm and width is 8 cm?

• 200 cm²

• 180 cm²

• 28 cm²

• 160 cm²

How is the length of line St determined?

• By subtracting the length of line QR from line pu

• By adding the lengths of lines QR and pu

• By measuring directly with a ruler

• By dividing the length of line pu by 2

What is the area of rectangle B if its length is 7 cm and width is 6 cm?

• 20 cm²

• 13 cm²

• 42 cm²

• 60 cm²

What is the total area of the figure?

• 202 cm²

• 160 cm²

• 42 cm²

• 180 cm²
