  1. Correct Answer – d
    According to rule of significant figures
    ●any zeros that are between non – zero also consider significant
    ● all none -zero digit significant.
    Hence , breadth of metel `b = 3.002m` has four significant figure
    `:.` Length of metal `= 3.124 m` has four significant figures.
    Since length and breadth have four significant therefore
    `”Area” = “length” xx “breadth”`
    `= 3.124 xx 3.002 = 9.378248`
    will also have four significant figures.
    Hence, `”area” = 9.378m^(2)`
