Calculating the Area of Parallelograms and Trapezia

The video tutorial explains the concept of area, focusing on how to calculate the area of parallelograms and trapeziums. It begins with a general introduction to area, emphasizing the multiplication of two dimensions and the use of squared units. The tutorial then delves into the specifics of calculating the area of a parallelogram by multiplying the base and height, while highlighting the importance of ignoring diagonals. It also covers the area of a trapezium, explaining a three-step process involving adding parallel sides, halving the sum, and multiplying by the height. The video concludes with examples and problem-solving techniques.

What is the area of a shape defined as?

• The length of the longest side of a shape

• The total space inside a 2D shape

• The volume of a 3D shape

• The perimeter of a 2D shape

How is the area of a parallelogram calculated?

• Base times height

• Length times width

• Diagonal times height

• Base times width

What characteristic is used to identify a parallelogram?

• Parallel opposite sides

• Equal angles

• Equal diagonals

• All sides equal

What is a unique feature of a trapezium?

• Two pairs of parallel sides

• One pair of parallel sides

• All sides are equal

• All angles are right angles

How do you calculate the area of a trapezium?

• Multiply the diagonals and divide by two

• Multiply the base by height

• Add the parallel sides, multiply by height, then divide by two
