Question

determine o perímetro de um retângulo com a base
$15 - 5 \sqrt{3}$
cm e altura de
$1 + 3 \sqrt{3}$
cm​

Answer 1

Oi

Usando a fórmula ...

$P=2.B+2.A\\\\\\\\P=2.(15-5\sqrt{3} )+2.(1+3\sqrt{3} )\\\\\\\\P=30-10\sqrt{3} +2+6\sqrt{3} \\\\\\\\P=30+2 +(-10+6)\sqrt{3} \\\\\\\\\boxed{\ P=32-4\sqrt{3} \ \ cm\ \ }$

Bons estudos! :)

Answer 2

b = 15 - 5√3 cm

a = 1 + 3√3 cm

P = 2b + 2a

P = 30 - 10√3 + 2 + 6√3

P = 32 - 4√3 cm
