Răspuns :
Aria=L×l
A=1,7×1,3=2,21 dm²
Perimetrul=2(L+l)
P=2(1,7+1,3)=2×3=6 dm
Răspuns:
- Formula arie dreptunghi
A = L × l
A = 1,7dm×1,3dm = 2,21 dm²
- Formula perimetru dreptunghi
P = 2L + 2l = 2(L + l)
P = 2(1,7dm + 1,3dm)
= 2×3dm = 6 dm
A=1,7×1,3=2,21 dm²
P=2(1,7+1,3)=2×3=6 dm
Răspuns:
A = L × l
A = 1,7dm×1,3dm = 2,21 dm²
P = 2L + 2l = 2(L + l)
P = 2(1,7dm + 1,3dm)
= 2×3dm = 6 dm
