![]() ![]() ![]() ![]() If the base of a triangular area is 200 ft and the height is 40 ft, the equation would beĪrea = (200 ft x 40 ft) ¸ 2 = 4000 ft 2 Calculating Rectangular Areas The equation for calculating the area of a triangle is as follows: Simply calculate the area for each individual shape and add them together.Ĭonversely, it may be necessary to compute the total square footage of structures within the area which will not be treated-buildings, patios, sidewalks, ponds, etc.-and subtract it from the overall area. Irregularly shaped flower beds, etc., usually can be divided into smaller, geometric areas (square, rectangle, circle, triangle) to facilitate total area calculation. To determine how much pesticide or fertilizer is needed to do a job, first calculate the size of the area to be treatedĬhances are that you don’t have a “geometrically perfect” area to treat. Rates for flowers, shrubs, and vegetables often are given per 100 square feet. Typically, use rates for lawn care products are stated per 1000 square feet or per acre. 39) HOW DO I CALCULATE THE AREA TO BE TREATED? (adapted from Purdue Pesticide Programs pub. This page will assist you in selecting products and calculating application rates for pesticides and lawn and garden fertilizers commonly used around the home. Using just the right amount of pesticide and fertilizer minimizes the potential for personal, property, or environmental damage and maximizes consumers’ return on the dollar. ![]()
