Question

if a carpenter measures the length of a board to be 1.32 m. and it's actual length is 1.25 m. what is the carpenter's percent error

Answer 1

\(\cfrac{\textbf{Calculated Value - Exact Value }}{\textbf{Exact Value}} \times 100\% \)

Here calculated value = 1.32 m
Actual / Exact value = 1.25 m

If the answer comes out to be as positive then it means that our calculated value was more than Exact value and if it comes out to be negative then it means Calculated value was less than the Exact value
