Answer:
The area of rectangle is 98 ft.sq.
Step-by-step explanation:
We are given one length of a rectangular garden lies along a patio wall.
Let the width of garden be x
Length of garden = Twice its width=2x
Length garden enclosed by fencing =l+2b=2x+2x= 4x
We are given that the rest of the garden is enclosed by 28 feet of fencing.
So,4x=28
x=7
Width of garden = 7 feet
length of garden = 2x=2(7)=14 feet
Area of garden = 
Hence The area of rectangle is 98 ft.sq.
37.8 x 7 = 264.6
Check:
264.6/7 = 37.8

Hope this Helps!!
Slope = Change in Y / change in x
Slope = (16 - -9) / (-2 - 3)
Slope = 25/-5
Slope = -5
R=xa+xb, r-xa=xb, b=r-xa/x
