1) P= 14 + 8 = 22cm
A= bxh: 7x4=28cm
-----------------------------------
2) P= 7 + 5 + 8,7 = 20,7cm
A= (bxh)/2: (8,7x4)/2 = 17,4cm
-------------------------------------------------
3) P= 13,6 + 8,4 = 22 m
A= (Dxd)/2: (5x5)/2= 25/2= 12,5m
----------------------------------------------------
4) P= 9,2 + 12,6= 21,8m
A= bxh: 6,3 x 4,10 25,83m
-----------------------------------------------
5) P= 24
A= L² = 36
------------------------------
6) P= 12 + 4 + 7= 23cm
A= (B+b)h/2: (7+4)5,8/2= 63,8/2= 31,9cm
