Fencing costs $20 per yard. * the length of the rectangular region will be 4 more yards than the width. * the farmer wants to have a total cost of $1,200. what will be the width, in yards, of the rectangular region?

27.5 yards

I hope this was helpful!

Step-by-step explanation:

So its 20$ per yard, the length is 4 more yards then the width. So that is a hundred dollars more then the width. You take away 100 from 1200; 1200-100= 1,100. so you divide 1,100 by 2 and get 550 and the length is 100 dollars more. so add 550+650 = 1,200, and so you know that is correct so then you divide 550 and 20 and you get 27.5.

So the width of the rectangular region is 27.5 yards.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
