min jun takes a sheet of paper and cuts from one corner to the opposite corner, making two triangles. if the piece of paper is 8 inches long and 12 inches wide , what is the perimeter of one of the triangles
The triangles will be RIGHT triangles with leg lengths of 8 and 12
Pythagorean theorem will give the length of the hypotenuse (which is the diagonal cut)
sqrt (8^2 + 12^2) = 14.42 in
The perimeter of ONE of these triangles is the sum of the sides 12 + 8 + 14.42 = 34.42 inches
