Annalisa, keiko, and stefan want to compare their heights. annalisa is 64 inches tall. stefan tells her, "i'm about 7.5 centimeters taller than you." keiko knows she is 1.5 inches shorter than stefan. give the heights of all three people in both inches and centimeters to the nearest half unit.

Height of Stefan and Keiko would be 170.06 cm and 168.56 cm respectively.

Step-by-step explanation:

Since we have given that

Height of Annalisa = 64 inches = 162.56 cm

According to question , Stefan is 7.5 cm shorter than Annalisa.

So, height of Stefan would be

162.56+7.5 = 170.06 cm

According to question , keiko is 1.5 inches than Stefan.

So, height of Keiko is given by

170.06-1.5 = 168.56.

Hence, height of Stefan and Keiko would be 170.06 cm and 168.56 cm respectively.
