Find the perimeter of the following figures : square, rectangle, triangle, parallelogram, trapezoid

__Exercise 1.1d__

**Find the perimeter of the
following figures.**

1) Perimeter = Sum
of all sides = 5 + 3 + 6 + 8 = 22 cm

Perimeter = 22 cm

2) Perimeter = Sum
of all sides = 7 + 2 + 5 + 10 = 24 cm

Perimeter = 24 cm

3) Perimeter = Sum
of all sides = 4 + 7 + 4 + 7 = 22 cm

Perimeter = 22 cm

4) Perimeter = Sum
of all sides = 11 + 11 + 11 + 11 = 44cm

Perimeter = 44 cm

5) Perimeter = Sum
of all sides = 5 + 5 + 10 + 10 = 30cm

Perimeter = 30cm

**Answer the following Questions.**

**1. A side of a square−shaped
sandbox in Gandhi Park measures 30 cm. Determine the perimeter of the sandbox.**

Side of a square shaped sand box = 30cm

Perimeter = Sum of all sides

= 30 + 30 + 30 + 30 = 120 cm

Perimeter of the sand box = 120 cm

**2. Find the perimeter of a
rectangle, whose sides are 12 cm and 8 cm.**

Side of a Rectangle = 12cm and 8cm

Perimeter = Sum of all sides

= 12 + 12 + 8 + 8 = 40 cm

Perimeter of the Rectangle = 40 cm

**3. Find the perimeter of the
triangle, whose sides are 13 cm, 5 cm and 14 cm.**

Side of a Triangle = 13cm, 15cm and 14cm

Perimeter = Sum of all sides

= 13 + 5 + 14 = 32cm

**Perimeter of the Triangle= 32 cm **

**4. The adjacent sides of a
parallelogram are 6 cm and 7 cm. What is the perimeter of the parallelogram?**

Side of a Parallelogram = 6cm and 7cm

Perimeter = Sum of all sides

= 6 + 6 + 7 + 7 = 26 cm

**Perimeter of the Parallelogram = 26 cm**

**5. The sides of a trapezoid measures
8 cm, 7 cm, 4 cm and 5 cm respectively. What is the perimeter of the trapezoid?**

Side of a Trapezoid = 8cm, 7cm, 4cm and 5cm

Perimeter = Sum of all sides

= 8 + 7 + 4 + 5 = 24 cm

**Perimeter of the Trapezoid = 24 cm**
