Answer 2

Answer:

a) 9 cm

b) 18.8 cm

Step-by-step explanation:

a) Let the side of square be s

Perimeter of square = 4*s

36 cm = 4s

36/4 = s

9 cm = s

b) Perimeter of remaining shape = Perimeter of rectangle - Perimeter of equilateral triangle

= (13+7.2+13+7.2) - (7.2+7.2+7.2)

= (40.4) - (21.6)

= 18.8 cm
