first solve for the perimeter of the rectangle
2w + 2l = 42
since the length of the rectangle is twice as long as the length and width of the square
2w = l
solve using substitution
2w + 2(2w) = 42
2w + 4w = 42
6w = 42
w = 7
are is length x width. a square has the same length and width
7 x 7 = 49
the area of one square is 49
Step-by-step explanation:
to be honest I'm not sure how to do
Figure #5 shows 5 squares which I would assume means (5, 5)
In the table you have the point (3, 7)
From this you can find the slope: (7 - 5)/(3 - 5) = -1
Completions of table:
x y
0 10
1 9
2 8
3 7
4 6
5 5
6 4
Rule/Equation:
y = -x + 10

She would need 45 Ft. of material. I hope this helped ^^
First, I multiplied the yards (2) by 3
Next, I Divided the inches (18) into Ft. which gave me 1 and a half Ft.
Then, I multiplied 6 Ft. with 6 and 1.5 Ft. with 6
Finally I added all of this together and got 45
