Question

1. Transformati in metri: 4dam; 5hm; 2475cm; 14573mm; 0,0124km.
2. Calculati in decimetri:
a) 0,125km + 14dam + 43,5m + 1243cm;
b) 5dam + 4320cm – 2,4m + 0,12hm
33. Calculati perimetrul unui triunghi daca laturile acestuia sunt: a=0,7dam; b=14dm;
c=4cm. Exprimati rezultatul in metri.

Dau coroana!

Answer 1

Explicație:

1) 4dam= 40m

5hm= 500m

2475cm= 24,75m

14573mm= 14,573m

0,0124km= 12,4m

2) a) 0,125km + 14dam + 43,5m + 1243cm

1250dm + 1400dm + 435dm + 124,3dm= 3209,5dm

b) 5dam + 4320cm - 2,4m + 0,12hm

500dm + 432dm - 24dm + 120dm = 1028dm

3) a=0,7dam= 7m

b=14dm= 1,4m

c=4cm= 0,04m

P= a+b+c=7+1,4+0,04= 8,44m
