Question

por favor no entiendo por favor ​

Answer 1

Explicación paso a paso:

a)

$area = \frac{2 \times 10cm \times 5cm}{2} = 50 {cm}^{2}$

$perimetro = (2 \times 10 + 2 \times 5)cm = 30cm$

b)

$area = ( \frac{6 \times 2}{2} + 6 \times 8) {cm}^{2} = 54 {cm}^{2}$

$perimetro = ( \sqrt{ {6}^{2} + {2}^{2} } + 2 +2 \times 8 + 6)cm =(2 \sqrt{10} + 24)cm$

c)

$area = (10 \times \frac{5 \times 3}{2} ) {cm}^{2} = 75 {cm}^{2}$

$perimetro = (6 \times 5)cm = 30cm$
