it is well known that a triangle ’ s area is √ ( p ( p - a ) ( p - b ) ( p - c ) ) , when p = ( a + b + c ) / 2 , such that a , b , c are the lengths of sides of the triangle . if the triangle has 300 , 300 , and 300 as the side ’ s lengths , what is the triangle ’ s area ?
it is well known that a triangle ’ s area is √ ( p ( p - a ) ( p - b ) ( p - c ) ) , when p = ( a + b + c ) / 2 , - > p = ( 300 + 300 + 300 ) / 2 = 450 , area = √ ( 450 ( 450 - 300 ) ( 450 - 300 ) ( 450 - 300 ) ) = 38,971 . therefore , the answer is e .
divide(sqrt(multiply(multiply(multiply(subtract(divide(add(add(300, 300), 300), 2), 300), subtract(divide(add(add(300, 300), 300), 2), 300)), subtract(divide(add(add(300, 300), 300), 2), 300)), divide(add(add(300, 300), 300), 2))), const_1000)
