Math Problem Statement

Find the area of the polygon in the image.

Solution

To find the area of the polygon in the image, we can divide the shape into simpler rectangles and then sum their areas. Here's the breakdown of the shape:

Step 1: Split the Polygon into Rectangles

  • Left Rectangle:

    • Width = 2 meters
    • Height = 9 meters
    • Area = 2×9=18m22 \times 9 = 18 \, \text{m}^2
  • Top Rectangle:

    • Width = 8 meters
    • Height = 4 meters
    • Area = 8×4=32m28 \times 4 = 32 \, \text{m}^2
  • Bottom Rectangle:

    • Width = 10 meters
    • Height = 5 meters
    • Area = 10×5=50m210 \times 5 = 50 \, \text{m}^2

Step 2: Add the Areas

18m2+32m2+50m2=100m218 \, \text{m}^2 + 32 \, \text{m}^2 + 50 \, \text{m}^2 = 100 \, \text{m}^2

Thus, the total area of the polygon is 100 square meters (m²).
