Answer 1

Answer:

1.) 3937cm

2.) 27977cm

3.) 11393cm

4.) 13144

Step-by-step explanation:

1.) To convert cm into m we need to we will multiply 15 to 100 and add 43 = 1543

On the other hand to convert cm into m we need to multiply 23 to 100 and add 94 = 2394

Then we have to add the both: 1543+2394= 3937

2.) Length of 1st net: 23m 43cm

Length of 2nd net: 25m 63cm

Length of both the nets:

Step 1: Convert into same unit:

1st net: 23×100+43=2343

2nd net: 25×100+63=2563

Add both: 2343+2563=27977

3.) Length of the wire brought by Agathiya to fence is garden: 70m 42cm

Length used by Agathiya to fence his garden: 43m51cm

Length of the wire remaining:

Step 1: Convert the numbers into same units

1st number: 70×100+42=7042

2nd number: 43×100+51=4351

Total length: 11393

4.) Material shopkeeper had: 93m75cm

Material shopkeeper sold: 37m69cm

Convert all numbers into same unit:

1st number: 93×100+75=9375

2nd number: 37×100+69= 3769

Material remained with shopkeeper:

Add both the numbers: 9375+3769= 13144

Hope it helped
