Farmer fernanda wants to put a fence around her rectangle field . the length of the field is 40 feet less than 3 times the width. if she has 320 feet of fencing, what are the dimensions of the field?

Length: 110 feet

Width: 50 feet

Step-by-step explanation:

we know that

The perimeter of rectangle is equal to

where

L is the length of rectangle

W is the width of rectangle

we have

so

----> equation A

----> equation B

Solve the system by substitution

substitute equation B in equation A

solve for W

Find the value of L

therefore

The dimensions of the field are

Length: 110 feet

Width: 50 feet

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
