Answer:
Total area of field sold(35*35)+(51*25)=2500
Area of square field is 2500
One side =
= 50
So, the perimeter of the square(4*a)=4*50=200
Cost of fencing = 200*1.5 usd = $300

Answer:
11
Step-by-step explanation:
To find the mean of a set of numbers, we add all of the numbers together and divide the sum by the size of the set. For that first set, we have three numbers, x, y and z, so the equation for their mean would be

We can rearrange this equation by multiplying both sides by 3, getting the equivalent equation

Let's do the same thing for the second mean:


With the two equations we've obtained, we can subtract (1) from (2) to get rid of x, y, and z, leaving us with

To find the mean of a and b now, all we have to do is divide both sides of the equation by 2, and we see that
