Question

Linda is estimating the length of a room in her house. the actual length of the room is 17 m. lindas estimate is 15 m. find the absolute error and the percent error of lindas estimate. if necessary, round your answers to the nearest tenth.​

Answer 1

2m and 11.8%

Explanation:

Absolute error is defined mathematically as:

Error/original value

[Original value - estimated value]

[17 - 15 ] = 2m

The percentage error would be

[Original value - estimated value]/ original value

[17 - 15 ] / 17 × 100%

0.1176 × 100% = 11.76%

11.8% [ to the nearest tenth]
