    a. 1.49%

    b. - 8.95%

    c. 0%

    d. - 1.49%

    Explanation:

    a. Actual length = 6.7 m

    Measured length = 6.8 m

    % error = (Measured length - Actual Length) / Actual Length * 100

    = (6.8-6.7) / 6.7 * 100 = 0.1/6.7 * 100 = 1.49%

    b. Actual length = 6.7 m

    Measured length = 6.1 m

    % error = (Measured length - Actual Length) / Actual Length * 100

    = (6.1-6.7) / 6.7 * 100 = - 0.6/6.7 * 100 = - 8.95%

    c. Actual length = 6.7 m

    Measured length = 6.7 m

    % error = (Measured length - Actual Length) / Actual Length * 100

    = (6.7-6.7) / 6.7 * 100 = 0.1/6.7 * 100 = 0%

    a. Actual length = 6.7 m

    Measured length = 6.6 m

    % error = (Measured length - Actual Length) / Actual Length * 100

    = (6.6-6.7) / 6.7 * 100 = - 0.1/6.7 * 100 = - 1.49%
