Area and Properties of Rectangles

This video tutorial explains how to find the area of composite shapes, specifically focusing on rectangles and triangles. It begins by reviewing the formulas for calculating the area of these shapes. The tutorial then demonstrates how to find the area of a composite shape that resembles a sideways L by dividing it into two rectangles. The process involves identifying the base and height of each rectangle and calculating their areas, which are then summed. The video also covers finding the area of a right trapezoid by dividing it into a rectangle and a triangle, calculating their areas, and adding them together to find the total area.

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

• Base minus height

• Base divided by height

• Base times height

• Base plus height

How can you divide a composite shape that looks like a sideways L?

• By drawing a diagonal line

If the opposite side of a rectangle is congruent, how can you find the missing base length?

• By measuring it directly

• By guessing

• By using the height

• By using the length of the opposite side
