a equilateral triangle having one side 5 m . in this triangle there is a square of side 2 m . calculate the percentage of area outside square in that triangle .
area of triangle = â ˆ š 3 a 2 / 4 . = 1.732 * 25 / 4 = 10.825 m 2 . area of square = 2 * 2 = 4 m 2 . rest area after square = 10.825 - 4 = 6.825 m 2 . % rest area after square = 6.825 / 10.825 * 100 = 63.04 % answer c
multiply(divide(subtract(multiply(divide(sqrt(const_3), const_4), power(5, const_2)), square_area(2)), multiply(divide(sqrt(const_3), const_4), power(5, const_2))), const_100)
