Answer 2

Given :

A certain household has consumed 200 units .

To Find :

Energy consumed in joules .

Solution :

We know , 1 unit is equal to 1 kWh energy i.e $3.6\times 10^6\ J$ .

So , 200 units will produce energy equal to :

$E=200\times 3.6\times10^6\ J\\\\E=7.2\times 10^8\ J$

Therefore , the energy in joule is $7.2\times 10^8\ J$ .
