Answer:
880 cm²
Explanation:
Extending the vertical segments divides the figure into three rectangles:
left: 7 cm by 13 cm
middle: 38 cm by 18 cm . . . . . (overall height is 8+7+23 = 38 cm)
right: 21 cm by 5 cm
The total area is the sum of the areas of these rectangles. Each area is the product of the rectangle dimensions.
A = (7 cm)(13 cm) +(38 cm)(18 cm) +(21 cm)(5 cm) = (91 +684 +105) cm²
A = 880 cm²
