Answer:
Harriet's estimated length is between 44.1 inches and 47 inches.
Step-by-step explanation:
Let the error be x.
so, x<4%
Now, if error is 1%
45 1/2 + 1% of 45 1/2
or, 91/2 + 1/ 100 × 91/2
= 46
Now,
45 1/2 - 1% of 45 1/2
or, 91/2 - 1/100 × 91/2
= 45.1
Now,
if error is 3%
45 1/2 + 3% of 45 1/2
or, 91/2 + 3/100 × 91/2
= 47
OR
45 1/2 - 3% of 45 1/2
= 91/2 - 3/100 × 91/2
= 44.1
