Question

calculati aria unui triunghi dreptunghic avand lungimile catetelor egale cu 0,5m si respectiv ,3,6 dm va rog dau coroana si ma si abonez

Answer 1

In primul rand faci transformarea:

0,5m=50cm

3,6dm=36cm

A=c1*c2/2

A=50*36/2

A=900cm=9m

Answer 2

Trasformam intai ce 3,6 dm in cm:

3,6 dm = 3,6×10=36 cm

Aria se calculeaza astfel:
$\frac{0.5 \times 36}{2} = \\ \frac{18}{2} = 9$
Sper ca e bine Succes!
