Question

2. The perimeter of the following figures are given, find the sides.
a) Perimeter of a square
800 m
b) Perimeter of a regular hexagon
2.4 km
c) Perimeter of a equilateral triangle
900 m​

Answer 1

Answer:

(i) The perimeter of equilateral triangle = 3 x side = 3 x 9.8 cm = 29.4 cm

(ii) Required perimeter = 13 cm + 13 cm + 10 cm = 36 cm

(iii) Perimeter of given pentagon = 5 x side = 5 x 8.2 cm = 41 cm

(iv) Perimeter of given hexagon = 6 x side = 6 x 6.5 cm = 39 cm

Answer 2

Step-by-step explanation:

Perimeter of a square = 800 m

⠀⠀⠀ ⠀⠀⠀⠀⠀⠀4a = 800 m

⠀⠀⠀⠀⠀ ⠀⠀⠀⠀a = 200 m

Perimeter of a regular hexagon = 2.4 km = 2400 m

⠀⠀⠀ ⠀⠀⠀⠀⠀⠀6a = 2400 m

⠀⠀⠀⠀⠀ ⠀⠀⠀⠀a = 400 m

Perimeter of a equilateral triangle = 900 m

⠀⠀⠀ ⠀⠀⠀⠀⠀⠀ 3a = 900 m

⠀ ⠀⠀⠀ ⠀ ⠀⠀⠀⠀a = 300 m
