Find the area of the figure. Assume all the angles are right angles and all the measurements are in cm.
We can split the figure into two rectangles.
The smaller rectangle has dimensions of 9 cm by 8 cm.
The larger rectangle has a length of 20 cm and a width of 18 cm - 8 cm = 10 cm. so its dimensions are 20 cm by 18 cm.
The area of the figure is thus 9 cm × 8 cm + 20 cm × 10 cm = 272 cm2.
