$T=144$ square meters
The area of this figure can be calculated by taking the area of the large rectangle, substracting the area of the little rectangle. The area of a rectangle can be calculated by: $T=a\times b$ where a and b are the lengths of the perpendicular sides. Here, the large rectangle: $T_1=12\times 13=156$ square meters The little rectangle: $T_2=3\times4 = 12$ square meters. The area of the figure: $T=T_1-T_2=156-12=144$ square meters
