Question

A solar panel generates 144 kW of energy. There are 13 such solar panels. How much energy is produced by all the solar panels?
(kW is the unit to measure energy.)

Answer 1

$\bullet$ Energy generated by 1 solar panel $=144\text{kW}$
$144\text{kW}=100+40+4\text{kW}$

$\bullet$ Number of such panels $=13$
$13=10+3$

Total energy generated $=144\times 13\text{kW}$
Let’s determine the cost using the partitioning method.

$\begin{array}{cccc}& 100& 40& 4\\ 10& 1000& 400& 40\\ 3& 300& 120& 12\end{array}$

Total energy generated $=1000+400+40+300+120+12=1,872\text{kW}$
