Question

cat inseamna 1/3 din 9048

Answer 1

$\frac{1}{3} \times 9048 = \frac{1 \times 9048}{3} = \frac{9048}{3} = 3016$

$P=9048\:m$

$l=\frac{1}{3} \times L+38=\frac{L}{3}+38$

$P=2(L+l)$

$9048=2(L+\frac{L}{3}+38)\:|\div \:2$

$4524=L+\frac{L}{3}+38\:|\times\:3$

$13572=3L+L+114$

$4L=13572-114$

$4L=13458\:|\div\:4$

$L=3364,5\:m$

$l=\frac{L}{3}+38$

$l=\frac{3364.5}{3}+38$

$l=1121,5+38$

$l=1159,5\:m$
