I will solve the perimeter problems for each figure shown in the worksheet. I'll calculate the perimeter of each shape by adding up the lengths of all its sides.
Let me start with the first figure, which is a rectangle.
First Figure (Rectangle):
- The top side is 8m.
- The right side is 5m.
- The bottom side is 8m.
- The left side is 5m.
- Perimeter = 8m + 5m + 8m + 5m = 26m
Second Figure (Triangle):
- The left side is 5m.
- The right side is 7m.
- The bottom side is 9m.
- Perimeter = 5m + 7m + 9m = 21m
Third Figure (Trapezoid):
- The top side is 3in.
- The right side is 9in.
- The bottom side is 10in.
- The left side is 9in.
- Perimeter = 3in + 9in + 10in + 9in = 31in
Fourth Figure (Irregular Quadrilateral):
- The top side is 8ft.
- The right side is 20ft.
- The bottom side is 23ft.
- The left side is 8ft.
- Perimeter = 8ft + 20ft + 23ft + 8ft = 59ft
Now I will provide the final answers for each figure.
The perimeters are:
- Rectangle: 26 meters
- Triangle: 21 meters
- Trapezoid: 31 inches
- Irregular quadrilateral: 59 feet
