Question

find the perimeter of the rectangle whose length and breadth are as give in the following table length 12 cm and breadth 19 mm​

Answer 1

Answer:

12+19 and you will get the answer

Answer 2

Given :-

Length of the rectangle = 12 cm

Breadth of the rectangle = 19 mm

To Find :-

The perimeter of the rectangle.

Analysis :-

Firstly, convert the length to millimeters.

Then substitute the values in the formula of perimeter of a rectangle and find the perimeter accordingly.

Solution :-

We know that,

• l = Length
• b = Breadth
• p = Perimeter

By the formula,

$\underline{\boxed{\sf Perimeter \ of \ rectangle=2(Length +Breadth) }}$

Given that,

Length (l) = 12 cm = 120 mm

Breadth (b) = 19 mm

Substituting their values,

Perimeter = 2(120 + 19)

= 2(139)

= 278 mm

Therefore, the perimeter of the rectangle is 278 mm.
