Let’s solve each problem one by one. Remember, perimeter means adding up all the sides of a shape.
---
1) Rhombus – side = 4 in.
A rhombus has 4 equal sides.
So, perimeter = 4 + 4 + 4 + 4 =
16 inches
Or: 4 × 4 = 16 in.
✔ Perimeter =
16 in.
---
2) Hexagon – side = 10 ft.
A regular hexagon has 6 equal sides.
Perimeter = 10 + 10 + 10 + 10 + 10 + 10 =
60 feet
Or: 6 × 10 = 60 ft.
✔ Perimeter =
60 ft.
---
3) Trapezoid – sides: 3 mm, 4 mm, 6 mm, 4 mm
Add all four sides:
3 + 4 + 6 + 4 = let’s do it step by step:
3 + 4 = 7
7 + 6 = 13
13 + 4 =
17 mm
✔ Perimeter =
17 mm
---
4) Parallelogram – sides: 8 m and 4 m
In a parallelogram, opposite sides are equal.
So we have two sides of 8 m and two sides of 4 m.
Perimeter = 8 + 4 + 8 + 4
Group them: (8 + 8) + (4 + 4) = 16 + 8 =
24 m
Or: 2×(8 + 4) = 2×12 = 24 m
✔ Perimeter =
24 m
---
5) Kite – sides: 2 cm, 2 cm, 5 cm, 5 cm
A kite has two pairs of equal adjacent sides.
So add: 2 + 2 + 5 + 5
2 + 2 = 4
5 + 5 = 10
4 + 10 =
14 cm
✔ Perimeter =
14 cm
---
6) Equilateral Triangle – side = 5 in.
All three sides are equal.
Perimeter = 5 + 5 + 5 =
15 inches
Or: 3 × 5 = 15 in.
✔ Perimeter =
15 in.
---
Final Answer:
1) 16 in.
2) 60 ft.
3) 17 mm
4) 24 m
5) 14 cm
6) 15 in.
