Question

The perimeter of a rectangle whose length is 6.5cm and breadth is 4.2

Answer 1

Answer:

21.4 Cm

Step-by-step explanation:

Given---->Length of rectangle is 6.5 Cm and

breadth of rectangle is 4.2 Cm

To find---> Perimeter of rectangle

Solution---> ATQ,

Length of rectangle = 6.5 Cm

Breadth of rectangle = 4.2 Cm

We know that,

Perimeter of rectangle = 2 ( length + breadth )

= 2 ( 6.5 + 4.2 )

= 2 ( 10.7 )

= 21.4 Cm

Additional information--->

1) Area of rectangle = length × breadth

2) Area of square = Side²

3) Perimeter of square = 4 ( Side )

4) Volume of Cube = edge³

5) Lateral surface area of cube = 4 ( edge² )

6) Total surface area of cube = 6 ( edge )²

7) Volume of cuboid = l × b × h

8) Lateral surface area = 2 ( l + b ) × h

9) Total surface area = 2 ( lb + bh + lh )
