Web1. Find the area of an equilateral triangle whose perimeter is 12 inches. Solution: Let the side of an equilateral triangle be a inches. Perimeter = 12 in. Perimeter of an equilateral triangle = 3a . 3a = 12 in. a = 4 in. Area = 3a24=3(4)24=1634=43 in2. 2. If the area of an equilateral triangle is 163 ft2, find the side of the triangle ... WebThis filter is rated FPR 10 which essentially equivalent to a MERV 13. MERV 13 provides very high filtering for your home furnace system. The higher the number, the finer the particles (the smaller the particles) that are trapped by the filter. MERV 8 (around a FPR 5) will capture pollen and dust and mites and mold spores.
