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

The video tutorial explains how to calculate the total weight of metal used in a rectangular frame with a diagonal. It begins by determining the perimeter of the rectangle, then uses Pythagoras' theorem to find the length of the diagonal. The total length of metal is calculated by adding the perimeter and diagonal lengths. Finally, the total weight is found by multiplying the total length by the weight per meter. The tutorial also discusses the marks distribution for solving the problem.
