AL = Pb.h
11cm² = Pb.13cm
11/13 cm = Pb

4l = Pb , donde: l = lado del cuadrado [base de la piramide]
4l = 11/13
l = 11/52  cm


.:. Area de la base = l² =(11/52)²


Por lo tanto:

Area total = Al + 2 Ab
Area total = [(11) + 2(11/52)² ]cm²
Area total = [(11) + 2(11/52)² ]cm²
Area total = 14993/1352  cm²  ≈ 11.09cm²
