Answer:
48cm
Explanation:
Given data
Dimension
12cmx16cm
Before we can get the perimeter of the resulting triangles
let us find the length of the diagonal
Diagonal
D^2= 12^2+ 16^2
D^2= 144+256
D^2= 400
D=√400
D=20cm
Hence the diagonal is 20cm
Therefore the perimeter of each triangle is
=12+16+20
=48cm
