To solve the problem of finding the perimeter of each polygon, we need to add up the lengths of all the sides of each shape. Let's go through each shape step by step.
Shape a: Triangle
- Sides: 4 cm, 5 cm, 6 cm
- Perimeter = 4 cm + 5 cm + 6 cm = 15 cm
Shape b: Rhombus
- All sides are equal: 9 ft
- Perimeter = 9 ft + 9 ft + 9 ft + 9 ft = 36 ft
Shape c: Pentagon
- Sides: 7 in, 8 in, 8 in, 7 in, 5 in
- Perimeter = 7 in + 8 in + 8 in + 7 in + 5 in = 35 in
Shape d: Parallelogram
- Opposite sides are equal: 12 mm and 10 mm
- Perimeter = 12 mm + 10 mm + 12 mm + 10 mm = 44 mm
Shape e: Trapezoid
- Sides: 4 km, 3 km, 4 km, 2 km
- Perimeter = 4 km + 3 km + 4 km + 2 km = 13 km
Shape f: Irregular Pentagon
- Sides: 6 ft, 4 ft, 8 ft, 4 ft, 3 ft
- Perimeter = 6 ft + 4 ft + 8 ft + 4 ft + 3 ft = 25 ft
Shape g: Triangle
- Sides: 7 cm, 10 cm, 15 cm
- Perimeter = 7 cm + 10 cm + 15 cm = 32 cm
Shape h: Rectangle
- Opposite sides are equal: 11 in and 9 in
- Perimeter = 11 in + 9 in + 11 in + 9 in = 40 in
Shape i: Regular Hexagon
- All sides are equal: 2 m
- Perimeter = 2 m + 2 m + 2 m + 2 m + 2 m + 2 m = 12 m
Final Answers:
-
a. 15 cm
-
b. 36 ft
-
c. 35 in
-
d. 44 mm
-
e. 13 km
-
f. 25 ft
-
g. 32 cm
-
h. 40 in
-
i. 12 m
Boxed Final Answer:
\[
\boxed{15 \text{ cm}, 36 \text{ ft}, 35 \text{ in}, 44 \text{ mm}, 13 \text{ km}, 25 \text{ ft}, 32 \text{ cm}, 40 \text{ in}, 12 \text{ m}}
\]
