You can put this solution on YOUR website!
formula : area =+%281%2F2%29%2Aa%2Ab%2Asin+%28x%29
where a, b are length of sides
x is the angle induced b/w those sides
hence
+24+=+%281%2F2%29%2A4%2A8%2Asin%28x%29
24+=+2%2A8%2Asin%28x%29
24=+16+sin%28x%29
sin(x)= 24/16
sin(x)=1.5
sin (x) cannot be more than 1 for any value of x
