Question

find the perimeter of the rectangle whose length one metre breadth 80 CM​

Answer 1

Given : Length of a rectangle is 1m and breadth of a rectangle is 80cm

To Find : Perimeter of the rectangle.

⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀____________________

Here

$\: \:$

• Length of the rectangle = 1m = 100cm
• Breadth of the rectangle = 80cm

$\: \:$

As we know that :

$\:$

$\star \: \underline{\boxed{\mathfrak\purple{Perimeter_{(rectangle)} = 2(l + b)}}}$

$\: \:$

Where l denotes length of the rectangle and b denotes breadth of the rectangle.

$\:$

Now, put the values and solve.

$\:$

$\sf:\implies \: Perimeter_{(rectangle)} = 2(l + b) \\ \\ \\ \sf:\implies \: Perimeter_{(rectangle)} = 2(100 + 80) \\ \\ \\ \sf:\implies \: Perimeter_{(rectangle)} = 2 \times 180 \\ \\ \\ \sf:\implies \: \underline{\boxed{\mathfrak\purple{Perimeter_{(rectangle)} = 360 \: cm}}}\bigstar \\ \\ \\ \\ \sf\therefore{\underline{Hence, \: the \: perimeter \: of \: the \: rectangle \: is \: \bold{360 \: cm}.}}$

Answer 2

Given :-

• Shape = Rectangle
• Length of the Rectangle = 1m = 100cm
• Breadth of the Rectangle = 80cm

To Find :-

• The Perimeter of the Rectangle

Solution :-

➞ Perimeter of Rectangle = 2( L + B )

➞ Perimeter of Rectangle = 2( 100 + 80 )

➞ Perimeter of Rectangle = 2 × 180

➞ Perimeter of Rectangle = 360cm

Therefore, Perimeter of the Rectangle = 360cm
