  Extracting the temperature of coronal loops is effective in the analysis of
solar active region's loops and helps in better understanding of coronal
events. To this end, various methods have already been developed like the
method developed by Aschwanden et al. 2015 \cite{AschwandenB2015} which is
based on Gaussian fit for Differential Emission Measure (DEM). Here, we use the
intensity ratios of the images in three different wavelengths and the
temperature response functions of AIA to extract the temperature of the loop.
In this paper, we use EUV images of the solar active region 11092 taken by AIA
instrument of the SDO satellite at 171, 193, and 211 $A^{0}$ wavelengths, at
1th of August, 2010. We select a loop in a subregion of 11092 and extract its
temperature by the help of intensity profiles in different wavelengths and
thermal response functions of different filters. In this subregion cooling of
the loop happens and in the selected loop, highest relative intensity of the
wavelengths of 171 $A^{0}$ to 193 $A^{0}$ was obtained to be $0.76$ and this
number was estimated to correspond to the temperature of 1.3 million degree of
Kelvin, which is the maximum temperature point of this loop's internal area.
The highest values of the intensity ratios at the wavelengths of 211$A^{0}$ to
193$A^{0}$, and 211$A^{0}$ to 171$A^{0}$ are $0.22$ and $0.25$, which
correspond to temperature values around 10M and 1.4M Kelvin in sequence,
related to the temperature of hotter and more superficial points of the loop
respectively. These values are very sensitive to time and differ in time series
of this event of the loop intensity variation.
