What if the star has a bigger surface area but a smaller temperature how would that affect the luminosity?

As temperature decreases, luminosity will also decrease
As radius increases (and with it surface area, but radius is a much easier to work with if you're trying to compare stars so we usually say radius) luminosity will also increase.
If both are happening at the same time, it is possible that the luminosity of the star will remain more or less constant. Often one change will dominate the other, such as when a star goes through the red giant phase when the increase in radius has a far greater effect than the drop in temperature, and the star becomes more luminous.

How would an increase in mass affect the basic properties of a star?
As mass increases It increases the surface temperature , luminosity, and radius.
What are the factors that affect the luminosity of the star?
Its size and temperature.
What factors affect the color of a star?
The temperature affects the color of a star.
How does the angle of the light affect the temperature of a surface?
How does the angle of light affect the temperature of a surface?
How do size temperature and distance affect a star's magnitude or luminousity?
A star's real luminosity is proportional to the the square of its diameter, and more or less proportional to the fourth power of its absolute temperature. The star's apparent luminosity is proportional to its real luminosity. It is also inversely proportional to the square of the distance.
How does temperature affect surface tension?
As the temperature rises, surface tension decreases.
How does dividing a solid into smaller pieces affect surface area?
It increases it.
How does a forest affect temperature?
The influence of a forest on temperature. The forest can lower the surface temperature on the surface during the season. The cool surface temperature allows for the growth of some vegetation that would not grow in the unprotected heat of the sun.
How would the sun's contract to a smaller volume affect the gravitational force on its surface?
It will be smaller so less gravity
How does the surface of an object affect its temperature?
Higher the surface area of an object, higher is its ability to radiate heat.
What are two factors that affect how fast water will evaporate?
Temperature and surface area
How would a lower angle of insolation affect the maximum temperature of a surface?
