Question

Actural length of a tope s 22.5 m but it is wrong measured as 21.6 m. find the percentage error.​

Answer 1

Step-by-step explanation:

Original length = 22.5m

False length = 21.6m

Error in length = 22.5 - 21.6

= 0.9m

Percentage error

= Error/Original length × 100

= 0.9/22.5 ×100

= 9/225 × 100

= (30/15)²

= 4%

Percentage error = 4%
