13. A table-top measures 2 m 25 cm by 1 m 50 cm. What is the perimeter of the table-top?​

Answer»

rong>Answer :

  • Perimeter of table- top is 7.5m

GIVEN :

  • A table - top measures 2m 25 cm by 1m 50 cm

To find :

  • Perimeter of the table-top

Solution :

Given,

  • Length of table = 2m 25m then,

》2m 25 cm

》2m + 25cm

》2 × 100cm + 25cm

》200cm + 25cm

》225 cm

Hence , Length of table is 225 cm

  • Breadth = 1m 50 cm

》1m 50cm

》1m + 50cm

》100cm + 50cm

》150 cm

Hence , Breadth of rectangle is 150M

Now we have to find the perimeter of table - top

  • Table - top is rectangle then,

As we KNOW that,

  • Perimeter of rectangle = 2(l + b)

where ,

  • Length of table - top = 225cm
  • Breadth of table - top = 150 cm

》2(length + breadth)

》2(225 + 150)

》2(375)

》750cm

Then

》750/100 m

1cm = 1/100m

》7.5m

Hence Perimeter of table - table is 7.5m
