Answer:
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards
Step-by-step explanation:
the perimeter of the rectangular yard needs to be 20 yards
Perimeter of a rectangle = 2 x ( length + width)
20 = 2 x ( length + width)
( length + width) = 20 /2
( length + width) = 10
The sum of the length and width should equal 10
Possible dimensions that would equal 10 are :
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards
<h3><u>

<h3><u>
Step-by-step explanation:</u></h3>
The formula that can be used to determine the distance from point C to point D is:

We know that distance between two points A(a,b) and B(c,d) is equal to the length of the line segment AB and is calculated by the help of the formula:

So, here we have:
(a,b)=(a,b) and (c,d)=(0,b)
