Question

Aflati aria unui patrat cu lungimea laturii de:a)1,2 m;b)3,4 m;c)0,13 dm;d)2,12 cm;e)3,25 m;f)14,2.va rog e urgent dau coroana cât mai repede plizzzzzzzzz

Answer 1

A(patratului) = l * l = l² 

a)  1,2m = (12/10)² =144/100=1,44 m²;
b)  3,4m =(34/10)² =1156/100=11,56 m² ;
c)   0,13dm=(13/100)² =169/10000=0,0169 dm² ;
d)  2,12cm=(212/100)² =44944/10000=4,4944 cm² ;
e)  3,25m=(325/100)² = 105625/10000=10,5625 m² ;
f)   14,2=(142/10)² = 20164/100 = 201,64 ;
