1. Problem Description

The problem asks to find the area of the polygon. The polygon can be decomposed into three rectangles. The dimensions are provided in the image. The area of a rectangle is given by the formula A=bhA = bh, where bb is the base and hh is the height.

2. Solution Steps

First, we identify the three rectangles.
Rectangle 1 has a base of 5 yd and a height of 13 yd.
Rectangle 2 has a base of 10 yd and a height of 9 yd.
Rectangle 3 has a base of 3 yd and a height of 13 yd.
Next, calculate the area of each rectangle.
Area1=5×13=65 yd2Area_1 = 5 \times 13 = 65 \text{ yd}^2
Area2=10×9=90 yd2Area_2 = 10 \times 9 = 90 \text{ yd}^2
Area3=3×13=39 yd2Area_3 = 3 \times 13 = 39 \text{ yd}^2
Finally, add the areas of the three rectangles to find the total area.
TotalArea=Area1+Area2+Area3Total Area = Area_1 + Area_2 + Area_3
TotalArea=65+90+39Total Area = 65 + 90 + 39
TotalArea=194Total Area = 194

3. Final Answer

The total area of the polygon is 194 yd2yd^2.
