An isosceles trapezoid has a perimeter of 57.5 kilometers. its shorter base measures 14.7 kilometers and its longer base measures 19.2 kilometers. the two remaining sides have the same length; what is that length?

Respuesta :

19.2 + 14.7 + 2x = 57.5
2x = 23.6
x = 11.8
each leg measures 11.8 kilometers
