Question

Va rog!Calculati mi perimentrul figurilor:) Eu am facut ceva , dar vreau rezolvarea corecta! Deci va rog mult!

Answer 1

Răspuns:

a. P dreptunghi=2(L+l)

lungimea=12 cm

latimea=4 cm

P=2(12+4)=>P=32 cm

b. P patrat=4L

latura = 16 cm

P=4×16=>P=64 cm

c. P=2(8+4)=>P=24 cm

Answer 2

$\it a)\ \ \mathcal{P}=2\cdot(L+\ell)=2\cdot(12+4)=2\cdot16=32\ cm\\ \\ b)\ \ \mathcal{P}=4\cdot\ell=4\cdot16=64\ cm\\ \\ c)\ \ \mathcal{P}=2\cdot4+2\cdot8=8+16=24\ cm$
