Question

A tabletop measures 3m 75cm by 2m 25cm. Find the perimeter of table top. ​

Answer 1

Answer:

Given, table-top dimension 2 m 25 cm by 1 m 50 cm

Length of the table top l=2.25 m

Breadth of the table top b=1.5 m ........... ∵1m=100cm

So, perimeter =2(l+b)

=2×(2.25+1.5)=7.5 m.

Answer 2

3m75cm=375cm

2m25cm=225cm

perimeter =2(l+b)

p=2(375+225)

p=2(600)

p=1200cm

p=12m
