Answer 1

Answer:

1] Breadth [a] 55 cm [b] 20 cm [c] 23.5 cm

Step-by-step explanation:

1] a] Perimeter of a rectangle = 2(length + breadth)

breadth = perimeter/2 - length

breadth = 160/2 - 25 cm

breadth = 80 - 25 cm

breadth = 55 cm

b] breadth = 160/2 - 60 cm

breadth = 80 - 60 cm

breadth = 20 cm

c] breadth = 160/2 - 56.5 cm

breadth = 80 - 56.5 cm

breadth = 23.5 cm
