Área largo (l) por ancho (a), luego el perimetro es 2 largos mas 2 anchos
l * a = 750
2l + 2a = 110 entonces l + a = 55 luego l = 55 - a sustituyendo
(55 - a) * a = 750
55 a - a² = 750 ⇒ 0 = a² - 55a + 750
a² - 55a + 750 = 0
a1 = 30 a2 = 25
R/ El largo es de 30 metros el ancho de 25 metros
Pruebas 30 m * 25 m = 750 m²
30 m + 25 m +30 m + 25 m = 110 m
