[tex]{h}^{2} = {13}^{2} - {12}^{2} \\ {h}^{2} = (13 + 12)(13 - 12) \\ {h}^{2} = (25)(1) \\ h = \sqrt{25} \\ h = 5[/tex]
Área del rectángulo.
[tex]a = b \times h \\ a = 12 \times 5 \\ a = 60 \: {cm}^{2} [/tex]
[tex]p = 4l \\ 20 = 4l \\ \frac{20}{4} = l \\ 5 = l[/tex]
Área del cuadrado.
[tex]a = {l}^{2} \\ a = {(5)}^{2} \\ a = 25 \: {cm}^{2} [/tex]
[tex]a = \frac{(b + B) \times h}{2} \\ a = \frac{(5 + 9) \times 8}{2} \\ a = \frac{14 \times 8}{2} \\ a = 7 \times 8 \\ a = 56 \: {cm}^{2} [/tex]
[tex]a = \frac{D1 \times D2}{2} \\ a = \frac{16 \times 12}{2} \\ a = 16 \times 6 \\ a = 96 \: {cm}^{2} [/tex]
