Answer 1

1a)

P=300+300+100+100+2L= 800+2L

2b)

Aria ABCD=300×50=15000 metri patrati

Aria BNPQ=100×L

Aria ABCD=Aria BNPQ rezulta

100×L=15000

L=15000:100

L=150m

c) Aria BNPQ= 150×100=15000m^2=1,5 hectare

2. a)

Diagonala cub=Lradical3

Rezulta L=6m

Volumul cub= l^3 (l puterea a treia inseamna)

V=6×6×6=216m^3
