Question

Calcule o perímetro de um retângulo cuja a base mede 18 Cm e altura, mede a metade da medida da base.​

Answer 1

$> \: resolucao \\ \\ \geqslant \: perimetro \: do \: retangulo \\ \\ b = 18cm \\ h = \frac{b}{2} = \frac{18}{2} = 9cm \\ \\ = = = = = = = = = = = = = \\ \\ p = 2(b + h) \\ p = 2(18 + 9) \\ p = 2 \times 27 \\ p = 54cm \\ \\ \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant$
