The length and the weight of the 12 pipe is found as 42 meters and 74.23 kg
<h3>What is referred as the unitary method?</h3>
- "It is a method in which we obtain the value of a single unit by subtracting the results of multiple units and thus the value of multiple units by subtracting the value of a single unit."
- We must first divide to discover the value of one thing, and then multiply to determine the significance of more or fewer things.
As, per the given question;
For, the seven pipes, the length is 24.5m.
7 pipes ---------> 24.5 m.
For the one pipe, use unitary method for solving;
Divide the equation by 7.
1 pipe -------->24.5/7 m.
For 12 pipes, multiply with 12 on both sides.
12 pipes --------> 24.5×12/7 m.
12 pipes ---------> 42 m.
Thus, the length of the 12 pipes is 42 meters.
Now, calculate the weight.
For, the seven pipes, the weight is 43.3 kg.
7 pipes ---------> 43.3 kg.
For the one pipe, use unitary method for solving;
Divide the equation by 7.
1 pipe -------->43.3 kg./7
For 12 pipes, multiply with 12 on both sides.
12 pipes --------> 43.3 kg×12/7
12 pipes ---------> 74.23
Thus, the weight of the 12 pipes is 74.23 kg.
