Question

Un dreptunghi are lungimea de 3 intreg si 1/5 m. Si latimea de 1 intreg si 1/4 ori mai mare decit lungimea. Aflati aria dreptunghiului.)

Answer 1

$3 \frac{1}{5}= \frac{16}{5}$
$1 \frac{1}{4} = \frac{5}{4}$
$\frac{16}{5} * \frac{5}{4}= \frac{80}{20} =4$
$A=L*l$
$A=\frac{16}{5} *4= \frac{64}{5}cm^2$
