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

The video tutorial explains how to calculate the total weight of a metal frame using basic geometry and arithmetic. It begins by identifying the components of the frame, including its perimeter and diagonal. The tutorial then demonstrates how to use Pythagoras' theorem to find the diagonal length and adds it to the perimeter to get the total length of metal used. Finally, it calculates the total weight by multiplying the total length by the weight per meter. The tutorial also discusses the marks distribution for the problem and provides tips for solving similar questions.
