Question
The base of a triangular plot is 25 meters, and its
height is 30 meters. If a path of 2 meters wide is to be built around the plot, what will be the area of the path?Solution
Area of the triangle = (1/2) * 25 * 30 = 375 square meters. New base after adding the path = 25 + 2 + 2 = 29 meters. New height after adding the path = 30 + 2 + 2 = 34 meters. New area of the triangle = (1/2) * 29 * 34 = 493 square meters. Area of the path = 493 - 375 = 118 square meters.
