Question

calculati aria unui dreptunghi ce re dimensunile a)=0,5,l=3,2
b)L=10,1cm,l=50mm
c)L=35dm ,l=200 cm
d) l=2,7 dam, l= 210 dm

Answer 1

Răspuns:

A= L×l

a) A= 0,5× 3,2

A=1,6cm^2

b) l= 50 mm= 5cm

A= 10,1×5

A=50,5cm^2

c)L= 35dm= 3,5cm

A= 3,5×200

A= 700cm^2

d)L=2,7dam= 2700cm

l= 210dm= 2100 cm

A= 2700×2100

A=5.670.000cm^2= 567 m^2

Sper ca te-am ajutat cu acest raspuns!!
