Question

Kwan bought three rolls of regular wrapping paper with 6.7 square meters of paper each.He also bought a roll of fancy wrapping paper containing 4.18 square meters.How much paper did he have altogether?

Answer 1

Answer: He had 24.28 m².

Explanation:

1. He bought 3 rolls of regular wrapping paper with 6.7 m². Then the total of this paper is:

`(3)(6.7m^(2))=20.1m^(2)`

2. He also bought a roll of fancy wrapping with 4.18 m². Therefore, to calculate the amount of paper he had together (which you can call
`x`), you must add 20.1 m² and 4.18 m², as you can see below:

`x=20.1m^(2)+4.18m^(2)\\x=24.28m^(2)`
