Question

Va rog exercițiul 10 macar punctele a si b!

Answer 1

Aria dreptunghiului = lungime (L) * latime (l)

a) A = L * l = 13 * 8 = 104 m

b) 12 dm = 1,2 m
A = L * l = 6,7 * 1,2 = 8,04 m

Answer 2

c) L=0,5 dam=5 m
l=3,2 m
A=L×l
A=5×3,2=16 m²

d) L=10,1 cm
l=50 mm=5 cm
A=L×l
A=10,1×5=50,5 cm²

e) L=35 dm
l=200 cm=20 dm
A=L×l
A=35×20=700 dm²

f) L=2,7 dam=270 dm
l=2100 dm
A=L×l
A=270×2100=567000 dm²
