Answer 2

Correct answer

Data:

length of iron rod = 20m

Weight of 20 cm of iron rod = 42kg

To find:

weight of 13m of iron rod =?

Solution:

1m iron bar weight = 42/20

weight of 13m of iron rod = ( 42/20 ) ×13

=( 21 / 10 ) × 13

= 21 × 13 / 10

= 273 / 10

= 27.3 Kg

Therefore, your answer is 27.3kg or 27kg.
