Answer:
The mass of one nickel is 5 grams.
Step-by-step explanation:
This question can be solved by proportions, using a rule of three.
In this question:
9 nickels have a mass of 45 grams. So one nickel will have a mass of:
9 nickels - 45 grams
1 nickel - x grams
Applying cross multiplication


The mass of one nickel is 5 grams.
A=x²
Substitute x with 1 4/5 or 9/5
A=(9/5)²
A=(9/5(9/5)
A=81/25
A=3.24. As a result, area of the square is 3.24 square units. Hope it help!
