Hello!
To find the total cost, we will need to multiply the cost per square meter, by the total area. To find the area we will use the formula A=<span>πr</span>². We will use 3.14 for pi.
We know that 2.1 is our radius. We will square it and then multiply it by 3.14.
2.1²=4.41
4.41(3.14)≈13.85
Our area is about 13.85. Now we will multiply by $1.70 to find the total cost. This gives us about $23.55.
The total cost of the glass would be about $23.55.
I hope this helps!
<span>x^2+5x+6=0
(x+3)(x+2) = 0
x+3 = 0
x = -3
</span>x+2 = 0
x = -2
<span>
Solutions: x = -3 and x = -2

The first thing we must do for this case is to find the relationship between the variables.
We have then:

From here, we clear the value of "Y":


On the other hand we have:

From here, we clear the value of "x":

Then, replacing values we have:

On the other hand:

Finally, the perimeter is given by:

Substituting values we have:

Answer:
the perimeter of ABCD is:
44 units
