The document provides tips for calculating the area of shapes. It gives an example of calculating the area of a semicircle with a radius of 3 cm using the formula A = πr^2/2. It shows identifying the shape as a semicircle, writing the formula, substituting the radius of 3 into the formula, and calculating the area as 14.13 square cm.
