What is the area of the figure? assessment graphic

OpenStudy (michele_laino):

we have to subtract the area of the white rectangle from the area of the larger rectangle, so we get: \(area=(11.6 \times 6)-(4 \times 3)=...?\)

OpenStudy (michele_laino):

for the second question, we can subdivide the geometrical shape in more rectangles, as below: |dw:1453502857788:dw|
