Răspuns: [tex]\bf \purple{\underline{ d_{2}=8~dm}}[/tex]
Explicație pas cu pas:
[tex]\red{\boxed{\bf Arie_{~romb}=\dfrac{d_{1}\cdot d_{2}}{2} }}[/tex]
[tex]\bf 44~dm^2=\dfrac{11~dm\cdot d_{2}}{2} \implies 11~dm\cdot d_{2}=2\cdot 44~dm^2[/tex]
[tex]\bf 11~dm\cdot d_{2}=2\cdot 44~dm^2~~~\bigg|_{:11~dm}[/tex]
[tex]\bf d_{2}=2\cdot 4~dm\implies \purple{\underline{ d_{2}=8~dm}}[/tex]
