Understanding Area Calculation of a Quadrilateral

The video tutorial explains how to calculate the area of a quadrilateral on a grid where each square is 1 square cm. It begins by counting the full unit squares covered by the shape and then addresses the partial squares, which are triangular sections. By combining these partial squares into full unit squares, the total area of the quadrilateral is determined to be 12 square cm.

What is the area of each unit square in the grid?

• 1 square cm

• 2 square cm

• 4 square cm

• 3 square cm

What shape is the figure whose area we need to calculate?

• Circle

• Quadrilateral

• Triangle

• Pentagon

How many full unit squares does the quadrilateral initially cover?

• 8

• 9

• 7

• 10

How many full unit squares are initially counted before considering the triangles?

• 5

• 6

• 7

• 9

What additional shapes are considered to complete the area calculation?

• Rectangles

• Triangles

• Circles

• Hexagons

What is the purpose of counting the small triangle-shaped areas?

• To find the perimeter

• To complete the area calculation

• To measure the height

• To determine the volume

What is the significance of combining two half-unit triangles?

• They form a new shape

• They increase the perimeter

• They reduce the area

• They create a full unit square

How many additional full unit squares are formed by combining half-unit triangles?

• 4

• 3

• 2

• 1

What is the total area covered by the quadrilateral?

• 11 square cm

• 12 square cm

• 10 square cm

• 13 square cm

What is the final step in determining the area of the quadrilateral?

• Dividing by the number of sides

• Multiplying the side lengths

• Adding the full unit squares

• Subtracting the perimeter
