Answer:

288 cm²

Explanation:

The figure decomposes into two rectangles and a triangle.

It is helpful to realize the overall horizontal length of the figure is 16+10+6 = 32 cm. That means the triangle at lower left has a width of 32-13 = 19 cm. Of course the bottom rectangle has a width of 10+6 = 16 cm.

The upper rectangle has an area of ...

A = LW = (6 cm)(4 cm) = 24 cm²

The lower rectangle has an area of ...

A = LW = (16 cm)(7 cm) = 112 cm²

The triangle has an area of ...

A = 1/2bh = 1/2(19 cm)(16 cm) = 152 cm²

__

Then the total area of the figure is ...

24 cm² +112 cm² +152 cm² = 288 cm²
