Question

a table top measure 2 metre 25 CM by 1metre15 CM. what is the perimeter of the table top​

Answer 1

Answer:

7 m

Step-by-step explanation:

Given-----> Length and breadth of tabletop measures 2 m25 cm by 1 m15 cm .

To find-----> Perimeter of the table top

Solution----> We know that ,

1 m = 100 Cm

ATQ,

Length of tabletop = 2 m 25 cm

= ( 2 × 100 ) cm + 25 cm

= ( 200 + 25 ) cm

= 225 cm

Breadth of tabletop = 1 m 15 cm

= 100 cm + 15 cm

= 115 cm

We know that , tabletop is rectangular ,

Perimetre of rectangle = 2 ( l + b )

Perimetre of rectangle = 2 ( l + b )

= 2 ( 225 + 125 )

= 2 ( 350 )

= 700 cm

= 700 / 100 m

= 7 m

Additional information------>

1) Area of rectangle = length × breadth

2) Area of square = Side²

3) Perimetre of square = 4 ( Side )
