Alenkinab [10]

Answer:

2.0491 watt per meter square

Step-by-step explanation:

We are given the following in the question:

The intensity of light is given by:

$I = \dfrac{W}{12.6r^2}$

where W is the wattage of the light bulb and r is the distance to the light bulb.

We have to evaluate the intensity of bulb with W = 100 watts and r = 2 meters.

Putting values, we get,

$I = \dfrac{100}{12.2(2)^2} = 2.0491\text{ watt per meter square}$

Thus, the intensity of light bulb is 2.0491 watt per meter square.
