Tu dijiste "el mismo perímetro que el rectangulo". Es rectangulo, o triangulo?
Si es el triangulo:
El triangulo tiene un lado 15 cm y uma diagonal 25 cm. Use el teorema de Pitágoras:
$${{\mathtt{a}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{{\mathtt{b}}}^{{\mathtt{2}}} = {{\mathtt{c}}}^{{\mathtt{2}}}$$
Entonces:
$${{\mathtt{15}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{{\mathtt{b}}}^{{\mathtt{2}}} = {{\mathtt{25}}}^{{\mathtt{2}}}$$
$${\mathtt{225}}{\mathtt{\,\small\textbf+\,}}{{\mathtt{b}}}^{{\mathtt{2}}} = {\mathtt{625}}$$
$${{\mathtt{b}}}^{{\mathtt{2}}} = {\mathtt{625}}{\mathtt{\,-\,}}{\mathtt{225}}$$
$${{\mathtt{b}}}^{{\mathtt{2}}} = {\mathtt{400}}$$
$${\mathtt{b}} = {\mathtt{20}}{cm}$$
Entonces, el perímetro del triangulo es:
$${\mathtt{P}} = {\mathtt{a}}{\mathtt{\,\small\textbf+\,}}{\mathtt{b}}{\mathtt{\,\small\textbf+\,}}{\mathtt{c}}$$
$${\mathtt{P}} = {\mathtt{15}}{\mathtt{\,\small\textbf+\,}}{\mathtt{20}}{\mathtt{\,\small\textbf+\,}}{\mathtt{25}}$$
$${\mathtt{P}} = {\mathtt{60}}{cm}$$
Entonces, el perímetro del cuadrado es 60 cm, tambien.
El lado del cuadrado es 60/4 = 15
Finalmente, el área del cuadrado es 15 * 15, = 225cm.
