GCSE Maths - How to Find the Area of Rectangles, Parallelograms, Triangles and Trapeziums #105

The video tutorial explains how to calculate the areas of rectangles, parallelograms, triangles, and trapeziums using specific formulas. It begins by defining the variables used in these formulas, such as length, width, base, height, and the top side of a trapezium. The tutorial then provides step-by-step instructions for calculating the area of each shape, including examples with measurements. It emphasizes the importance of understanding the formulas and the reasoning behind them, such as the use of 1/2 in the triangle area formula to account for its shape.

What is the significance of the vertical height in the area calculations?

Why do we multiply the triangle's base and height by 1/2?

How do you find the area of a trapezium?
