Question

The length of a rectangle is 20cm. and breadth is 0.5m. find out the perimeter in cm. and m.
​

Answer 1

Answer:

answer is 2.05

Answer 2

Given :-

• The length of a rectangle is 20cm
• The breadth of a rectangle is 0.5m

To Find :-

• The perimeter in cm and m

Formula to be used :-

Perimeter of rectangle = 2 ( l + b )

Where as

• Length ( L ) = 20 cm

• Breadth ( B ) = 0.5 m

Solution :-

In cm, Perimeter of rectangle

= 2 ( l + b )

= 2 ( 20 cm + 0.5 × 100 cm )

= 2 ( 20 cm + 50 cm )

= 2 × 70 cm

= 140 cm

In m , perimeter of rectangle

= 2 ( l + b )

= 2 ( 20/100m + 0.5 m )

= 2 × ( 0.2 + 0.5 )

= 2 × 0.7

= 1.4 m

Answer :-

Therefore the perimeter of the given rectangle

is 140 cm or 1.4 m
