GCSE Secondary Maths Age 13-17 - Geometry & Measures: Parallelogram - Explained

The video tutorial explains how to calculate the area of a parallelogram using given dimensions and angles. It starts by introducing the problem and the need to remember the area formula, which is the base multiplied by the vertical height. The tutorial then demonstrates how to find the height using trigonometry, specifically the sine function, in a right-angled triangle. After calculating the height, the area is determined by multiplying the base by the height. The video concludes with a discussion on marks allocation and common mistakes students make, emphasizing the importance of knowing the formula.

What is the final area of the parallelogram rounded to one decimal place?

Explain why understanding the formula for the area of a parallelogram is important.
