Answer 1

Explicație pas cu pas:

$\dfrac{\mathcal A_{1}}{\mathcal A_{2}} = \dfrac{{\ell_{1}}^{2}}{{\ell_{2}}^{2}} = {\bigg(\dfrac{\ell_{1}}{\ell_{2}} \bigg)}^{2}$

${\bigg(\dfrac{\ell_{1}}{\ell_{2}} \bigg)}^{2} = \dfrac{1}{4} = {\bigg(\dfrac{1}{2} \bigg)}^{2}$

$\dfrac{\ell_{1}}{\ell_{2}} = \dfrac{1}{2} \iff \dfrac{4\ell_{1}}{4\ell_{2}} = \dfrac{1}{2}$

$\implies \dfrac{\mathcal P_{1}}{\mathcal P_{2}} = \dfrac{1}{2}$
