Answer:

  760 ft²

Step-by-step explanation:

Extending the horizontal lines divides this rectangle into three rectangular parts:

  top: 11 ft by 16 ft

  middle: 24 ft by 21 ft

  bottom: 10 ft by 8 ft

The total area is the sum of the areas of these rectangles, found by multiplying length by width.

  A = (11×16 +24×21 +10×8) ft² = (176 +504 +80) ft² = 760 ft²

Solution:

Find the area of the unshaded region(s):

  • (11 x 5) + (6 x 10) + (7 x 10)
  • => (55) + (60) + (70)
  • => 185 ft²

Find the area of the rectangle (Refer to image):

  • 45 x 21
  • => 945

Subtract the area of the unshaded region from the area of the rectangle.

  • 945 - 185
  • => 760 ft²

The area of the figure is 760 ft².
