Work Step by Step

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: $T_1=30\times 60=1800$ square centimeters The little rectangle: $T_2=35\times5 = 175$ square centimeters. The area of the figure: $T=T_1-T_2=1800-175=1625$ square centimeters
