Answer 2

Answer:

• Let the Breadth be x cm.

Then,

• Length will be 4x + 2 cm.

❍ According to Question now,

➥ Perimeter of reactangle = 2 (Length + Breadth)

➥ 28 = 2(x + 4x + 2)

➥ 28 = 2x + 8x + 4

➥ 28 - 4 = 10x

➥ 24 = 10x

➥ x = 24/10

➥ x = 2.4 cm

Therefore,

• Length = 2.4 cm

• Breadth = 4(2.4) + 2 = 11.6 cm
