Perimeter of each triangle is #41.0# cm

Explanation:

Diagonal of #12# cm square is # sqrt(12^2+12^2)=12 sqrt 2# cm

#3# sides of each right triangle are #(12,12 and 12 sqrt 2)#cm

Perimeter of each triangle is #P= (12+12 +12 sqrt 2)#cm

or #P= (12+12 +16.97) ~~ 40.97~~ 41.0# cm

Perimeter of each triangle is #41.0# cm [Ans]
