Question

O parcelă de formă dreptunghiulara are laturile a=300 si b=400m. Calculati aria parcelei in m², dam² si hm² ​

Answer 1

Răspuns: A = 120 000 m² = 1200 dam² = 12 hm²

Aria dreptunghiului = Lungime x latime

L ungime =  400 m = 40 dam = 4 hm

latime =  300 m = 30 dam = 3 hm

aria in m²= 400 m x 300 m = 120 000 m²

aria in dam² =  40 dam x 30 dam = 1200 dam²

 aria in hm² =   4 hm x 3 hm = 12 hm²
