    Answer:

    Percent error=1.23%

    Step-by-step explanation:

    We are given that

    Estimate length of room=20 feet

    Actual length of room=20.25 feet

    We have to find the percent error.

    To find the percent error we will find the difference between the estimate length and actual length of room.

    Difference=Actual length of room-Estimate length of room

    Difference=20.25-20

    Difference=0.25 feet

    Now,

    Percent error=\frac{Difference}{actual\;length}\times 100

    Percent error=\frac{0.25}{20.25}\times 100

    Percent error=1.23%
