Answer 1

Answer:

182.5cm or 121.6cm

Step-by-step explanation:

error rate=20%

let original height be x, ie, 152cm

assuming the incorrect height is 20% more than the original height

so,

measure of error=20% of x=30.4cm

measure of incorrect height=(20% of x) + x =30.4+152=182.4cm

If, the incorrect height is 20% less than original height

then,

measure of incorrect height= 152-30.4 =121.6cm
