Question

calculati aria unui romb care are o diagonala de 4 cm si cealalta diag de 6 cm

Answer 1

Aria unui romb o putem calcula cu ajutorul formulei A=d1+d2/2

d1= diagonala 1

d2=diagonala 2

Rezolvare:

A= (4+6)/2

A=5 cm pătrați

Answer 2

$\it \mathcal{A}_{romb}=\dfrac{d_1\cdot d_2}{2}=\dfrac{4\cdot6}{2}=\dfrac{24}{2}=12\ cm^2$
