Find the length of the metal strip
required to frame a picture of length
54 cm and breadth 39 cm.​

Answer 1

Answer:

Length of metal strip required to frame the picture is 186 cm.

Step-by-step explanation:

Since we have to frame the picture from all sides, we would be requiring perimeter of the picture.( i.e. a rectangular object ).

From the properties of quadrilaterals :

• Perimeter of rectangle = 2( length + breadth )

Here,

Length of picture is 54 cm and breadth is 39 cm.

Therefore,

= > Perimeter of the picture = 2( 54 cm + 39 cm )

= > Perimeter of the picture = 2( 93 cm )

= > Perimeter of the picture = 186 cm

Hence the length of metal strip required to frame the picture is 186 cm.
