Question

Determine a área dos losangos a seguir,
em centimetro quadrado.

Answer 1

Explicação passo-a-passo:

a)

$\sf S=\dfrac{D\cdot d}{2}$

$\sf S=\dfrac{10\cdot5}{2}$

$\sf S=\dfrac{50}{2}$

$\sf S=25~cm^2$

b)

$\sf S=\dfrac{D\cdot d}{2}$

$\sf S=\dfrac{8\sqrt{2}\cdot4\sqrt{2}}{2}$

$\sf S=\dfrac{8\cdot4\cdot2}{2}$

$\sf S=\dfrac{64}{2}$

$\sf S=32~cm^2$

Answer 2

Resposta:

a 10.5/2=50/2=25

b 8√2.4√2=32√4=32.2=64
