Sample Problem

Find the area of the figure. Assume all the angles are right angles and all the measurements are in cm.


Description: Description: 93.28.JPG


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.
