Question

Calculati aria unui dreptunghi ce are dimensiunea :
a)L=13 m, l=8 m b)L=6,7 m, l=12 dm
c)L=0,5 dam, l=3,2 m d)L=10,1 cm , l=50 mm
e)L=35 dm , l=200 cm f)L=2,7 dam , l= 2100 dm

Answer 1

a) 13m*8m=108$m^{2}$
b) 6,7m*12dm=6,7m*1,2m=8,04$m^{2}$
c) 0,5dam*3,2m=5m*3,2m=16m$m^{2}$
d) 10,1cm*50mm=0,101m*0,05m=0,00505$m^{2}$
e) 5dam*3,2m=50m*3,2m=160m$m^{2}$
f) 2,7dam*2100dm=27m*210m=5670$m^{2}$
