Question

Raportul dintre arile a doua patrate are valoarea 0,09. Aflati raportul dintre lungimea laturilor lor

Answer 1

$\frac{A_1}{A_2}=0,09 \\\\ \frac{A_1}{A_2}=\frac{9}{100} \\\\ \frac{l_1^2}{l_2^2}=\frac{9}{100} \\\\ \frac{\sqrt{l_1^2}}{\sqrt{l_2^2}}=\frac{\sqrt{9}}{\sqrt{100}} \\\\ \boxed{\frac{l_1}{l_2}=\frac{3}{10}}}$

Answer 2

A1 / A2 = 0, 09
A1 / A2 = 9 /100
A patrat = l²
l²1 / l²2 = 9 /100
√l² 1 / √l²2 = √9 / √100
l1 / l2 = 3 /10
