Question

Find the missing length if the perimeter of the the rectangle is 36 cm and length 12m ​

Answer 1

Answer:

The missing length of the rectangle is 6m.

Step-by-step explanation:

Perimeter of rectangle = 2 ( l + b )

Here, l = length and b = breadth i.e the missing length.

So according to the formula,

36 = 2 ( 12 + b )

36 = 24 + 2b

36 - 24 = 2b

12 = 2b

therefore, b = 6m

As 'b' ( breadth ) is the missing length

therefore the length of missing length is 6m.
