Question

The perimeter of rectangle is 40cm and its breadth is 8cm.Find its length ​

Answer 1

Answer:

Let length of rectangle be X cm. X = 12 cm. Hence, Length of rectangle = X = 12 cm.

Answer 2

Answer:

length = 12cm

Step-by-step explanation:

Perimeter of a rectangle = 2(length + breadth)

Given that breadth = 8 cm

Perimeter of the rectangle = 40cm

Therefore,

40 = 2(length + 8)

40=2(length) + 16

40 - 16 = 2(length)

24 = 2(length)

Therefore

length = 24/2

length = 12 cm
