Question

A carpenter has two pieces of wood which are 35 m
20 cm and 47 m 47 cm long respectively. Which one is
longer and by how much ? Also find the total length
of wood if he joined both pieces?​

Answer 1

Answer:

length of first wood (A)= 35.2m

length of second wood(B) = 47.47 m

hence, A<B

so , B is longer by (47.47-35.2)m =12.27m

Now, total length = (47.47+35.2)m=82.67m

Answer 2

Answer:

the second one is longer

total length 8287

convert meter into cm

35*100= 3500

3500+20cm

3520cm

47*100=4700

4700+47

4747

and for the second part: 4747+3020= 8287
