Hi Udit, The exclusion zone consists of a 1 mile wide rectangular strip along each side and a sector of a circle at each vertex of the triangle. Here is a close up at one vertex with the exclusion zone coloured blue. You can calculate the area of the circular section of the exclusion zone if you know the measure of its central angle. What do you know about the measures of a triangle that has side lengths 3, 4 and 5 units? Penny | ||||||||||||
