Respuesta :

Total height = 1yd + 1yd+1/3yd = 2 1/3 yd = 7/3 yd

7/3 yd  = 7/3 * 36 inch = 84 inch

Answer:

84 inches

Step-by-step explanation:

A girl is exactly one yard tall.

one yard = 36 inches

Her sister is 1/3 of a yard taller = 36 + [tex](\frac{1}{3}\times 36)[/tex]

                                                   = 36 + 12

                                                   = 48 inches

Total inches when they added together = 48 + 36 = 84 inches
