GCSE Secondary Maths Age 13-17 - Shapes & Area: Trapezium/Circle Area - Explained

The video tutorial explains how to calculate the area of a shaded region formed by a trapezium and two semi-circles. It covers the steps to find the area of the trapezium using a specific formula, then calculates the area of the semi-circles by treating them as a full circle. The final step involves subtracting the area of the semi-circles from the trapezium and rounding the result to three significant figures. The tutorial also highlights the importance of remembering formulas and understanding key concepts for exams.
