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

The video tutorial addresses a starred question involving the calculation of the perimeter of a trapezium-shaped field. The farmer has 50 meters of fencing, and the task is to determine if this is sufficient. The tutorial explains how to find the missing side using Pythagoras' theorem and calculates the total perimeter, concluding that the farmer does not have enough fencing. The video also outlines the marking scheme for the question.

Explain how Pythagoras's theorem is applied in this problem.

What is the final perimeter of the farmer's field, and how did you arrive at that conclusion?
