Question

A pole is of a certain length. If 0.35 m of the pole is painted red, 1.37 m is painted white, 3.27 m is painted black and the remaining 5.63 m is left unpainted, then find the length of the pole rounded off to the nearest integer.

Answer 1

The total length of the pole is the portion that is painted red, white, black and the portion left unpainted.
The total length of the pole is = 0.35 + 1.37 + 3.27 + 5.63

$0.35$
$+1.37$
$+3.27$
$+5.63$
$\overline{}$
$10.62$
$\overline{}$

The total length of the pole is 10.62 m

Rounding it off to the nearest integer, we get the length as 11 m.
