This experience report describes a practical lesson carried out with a 2nd year high school class to calculate the area of a trapezoid-shaped court, without the direct use of conventional formulas. The activity was carried out in five stages: presenting the problem, measuring the edges, building a geometric model, decomposing the trapezoid into simple geometric figures and calculating the total area by approximation. The students used basic tools such as ropes, tape measures and calculators to carry out the measurements and calculations. The experiment aimed to stimulate problem-solving skills, as well as demonstrating that alternative calculation methods can be efficient. At the end, the approximate area was compared with the exact calculation, highlighting the effectiveness of the method.
