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.

Step-by-step 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:

$x=20.1m^{2}+4.18m^{2}\\x=24.28m^{2}$
