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 Reply

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
