Question

The perimeter of rectangle whose length is 20 m and breadth is 21 m

Answer 1

Answer:

perimeter of rectangle = 2( l + b )

2 ( 20 + 21 )

2 ( 41 )

82

so , the perimeter is 82 m..

Answer 2

given:

length of the rectangle = 20m

breadth of the rectangle = 21 m

:. perimeter of the rectangle = 2 ( l + b )

= 2 ( 20 + 21 )

= 2 ( 41)

= 82 m^2

:. perimeter of the rectangle = 82 m^2
