Let’s solve each shape one by one.
Perimeter means adding up all the sides of a shape.
---
Top Row:
1.
Blue Square (4 cm on each side)
All 4 sides are 4 cm.
Perimeter = 4 + 4 + 4 + 4 =
16 cm
2.
Orange Rectangle (6 ft long, 2 ft wide)
Opposite sides are equal. So two sides are 6 ft, two are 2 ft.
Perimeter = 6 + 2 + 6 + 2 =
16 ft
3.
Red Triangle (all sides 8 inch)
It’s an equilateral triangle — all sides same.
Perimeter = 8 + 8 + 8 =
24 inch
---
Middle Row:
4.
Green Parallelogram (sides: 5 m, 6 m, 5 m, 6 m)
Opposite sides equal.
Perimeter = 5 + 6 + 5 + 6 =
22 m
5.
Purple Trapezoid (sides: 6 cm, 9 cm, 2 cm, 2 cm)
Add all four sides:
6 + 9 + 2 + 2 =
19 cm
6.
Blue Right Triangle (sides: 9 ft, 7 ft, 5 ft)
Just add them:
9 + 7 + 5 =
21 ft
---
Bottom Row:
7.
Orange Hexagon (all sides 9 cm)
6 sides, each 9 cm.
Perimeter = 9 × 6 =
54 cm
8.
Blue Rectangle (7 m tall, 4 m wide)
Two sides 7 m, two sides 4 m.
Perimeter = 7 + 4 + 7 + 4 =
22 m
9.
Red Isosceles Triangle (two sides 12 ft, base 10 ft)
Add: 12 + 12 + 10 =
34 ft
---
Final Answer:
16 cm, 16 ft, 24 inch, 22 m, 19 cm, 21 ft, 54 cm, 22 m, 34 ft
