a)
P = a*h = 3,4 m * 2 m = 6,8 m^2
------------------------------------
b)
P = (1/2) a*h = (1/2) *3,4 dm * 20 dm = 34 dm^2
-----------------------------------------------
c)
P = 0,5*[a + b}*h = 0,5* [ 1,2 + 700 ] dm * 0,55 dm = 192,83 dm^2
---------------------------------------------------------------
d)
P = a*b = 2,6 cm * 3,4 cm = 8,84 cm^2
