In the diagram, all distances shown are in cm. The perimeter of the shape is 60 cm. What is the area, in cm2, of the shape?
A. 192
B. 204
C. 212
D. 232
E. 252
A. 192
Let the length of the right hand edge of the shape be h cm. Then 2(h + 18) = 60.
Therefore h = 12.So the area, in cm2, of the shape is 18 × 12 − 6 × (12 − 8) = 216 − 6 × 4 = 216 − 24 = 192.
