Question

the length and breadth of rectangle are 12cm and 9cm respectively. find the side of the square with perimeter equal to that of the rectangle​

Answer 1

$\large{\boxed{\bf{Answer}}}$

Side of square = 10.5 cm

__________________________

Given :-

• Length of the rectangle = 12cm

• Breadth of the rectangle = 9cm

• Perimeter of rectangle = Perimeter of square

To Find :-

• Side of the square

__________________________

$\large{\boxed{\bf{Solution}}}$

• Length and breadth of the rectangle = 12cm and 9cm

★ Perimeter of rectangle = 2 (length + breadth)

=> 2 ( 12 + 9 )

=> 2 × 21

=> 42 cm

Perimeter of rectangle = Perimeter of square = 42cm

★ Perimeter of square = 4 × side

=> 42 = 4 × side

=> side = 42/4

=> side = 10.5 cm

Hence, the side of square = 10.5cm.
