To find the perimeter of a quadrilateral (a four-sided shape), you simply add up the lengths of all four sides.
Here are the step-by-step calculations for each problem:
1. Square
* Sides: 14 ft, 14 ft, 14 ft, 14 ft
* Calculation: $14 + 14 + 14 + 14 = 56$
* Perimeter:
56 ft
2. Rectangle
* Sides: 9 in, 3 in, 9 in, 3 in
* Calculation: $9 + 3 + 9 + 3 = 24$
* Perimeter:
24 in
3. Parallelogram
* Sides: 8 yd, 10 yd, 8 yd, 10 yd
* Calculation: $8 + 10 + 8 + 10 = 36$
* Perimeter:
36 yd
4. Trapezoid
* Sides: 10 m, 7 m, 12 m, 7 m
* Calculation: $10 + 7 + 12 + 7 = 36$
* Perimeter:
36 m
5. Rhombus
* Sides: 6 km, 6 km, 6 km, 6 km
* Calculation: $6 + 6 + 6 + 6 = 24$
* Perimeter:
24 km
6. Quadrilateral
* Sides: 5 cm, 7 cm, 6 cm, 8 cm
* Calculation: $5 + 7 + 6 + 8 = 26$
* Perimeter:
26 cm
7. Rectangle
* Sides: 2 yd, 9 yd, 2 yd, 9 yd
* Calculation: $2 + 9 + 2 + 9 = 22$
* Perimeter:
22 yd
8. Parallelogram
* Sides: 4 mi, 10 mi, 4 mi, 10 mi
* Calculation: $4 + 10 + 4 + 10 = 28$
* Perimeter:
28 mi
9. Trapezoid
* Sides: 5 ft, 10 ft, 6 ft, 12 ft
* Calculation: $5 + 10 + 6 + 12 = 33$
* Perimeter:
33 ft
Final Answer:
1. 56 ft
2. 24 in
3. 36 yd
4. 36 m
5. 24 km
6. 26 cm
7. 22 yd
8. 28 mi
9. 33 ft
