Best ResponseYou've already chosen the best response.0 x1 y1 1 x2 y2 1* +/ 1/2 x3 y3 1 Is the formula to find the area of triangle using determinants. Put the values: 2 3 1 1/2 2 1 3 2 1 Expand using 1st row, 2(22)3(1/2+3)+1(16) 83(7/2)+1(5) 1/2(821/25) 1/2(1321/2) 1/2(47/2) 47/4 square units. is your answer. NOTE: We are writing +1/2 or 1/2 because we need the final answer in +ve if it is ve inside bracket, then we multiply by 1/2 to get positive answer and if not, +1/2. Hope this helps!
