Calculating Areas of Polygons

The video tutorial explains how to calculate the area of a polygon composed of a rectangle and a triangle. It begins by introducing the concept of area calculation, then demonstrates how to find the area of the rectangle using its base and height. Next, it covers the calculation of the triangle's area using its base and height. Finally, the tutorial combines the areas of the rectangle and triangle to find the total area of the polygon.

• Base times height

• Base divided by height

• Base minus height

What is the area of the rectangle in the polygon?

• 48 square cm

• 36 square cm

• 60 square cm

• 54 square cm

What formula is used to calculate the area of a triangle?

• Base times height

• Base plus height

• 1/2 times base times height

• Base minus height

What is the total area of the polygon?

• 65 square cm

• 58 square cm

• 63 square cm

• 60 square cm
