GCSE Secondary Maths Age 13-17 - Shapes & Area: Perimeter And Areas - Explained

The video tutorial explains how to draw a triangle with the same area as a given trapezium on a centimeter grid. It begins by calculating the area of the trapezium using the formula (1/2) * (a + b) * h, where a and b are the lengths of the parallel sides, and h is the height. The area is found to be 18 squares. The tutorial then demonstrates how to draw a triangle with an area of 18 squares by selecting a base and height whose product is 36. The video concludes with exam tips, emphasizing the importance of remembering formulas.
