Kruka [31]

Answer: 9 cm

Step-by-step explanation:

The formula of the area of a square is

A = s²

The ‘A‘ stands for area and the ‘s’ stands for side measure.

Now, since you already know the side measure, it’s 3cm, you just have to put it into the equation.

So, now you have:

A = 3²

A = 9

Therefore, the area of the square is 9 cm.

aleksandrvk [35]

Answer:

The system cannot be solved by a unique cost for each soldier, because has infinite solutions

Step-by-step explanation:

Let

x-------> the cost of a legionary per day

y-------> the cost of an archer per day

we know that

$4x+4y=10$ ------> equation A

$2x+2y=5$ ------> equation B

Multiply equation B by $2$ both sides

$2(2x+2y)=2*5$ -------> $4x+4y=10$

equation A and equation B is the same equation

therefore

This is a consistent dependent system

The system has infinite solutions
