Answer:
The wide of the walkway is 5ft.
Step-by-step explanation:
In first place you have a rectangular garden of 30ft by 40 ft as shown in Figure 1 (Added file).
So, the area of this rectangle is:
Area=1200ft
Now, the new garden has a walkway of uniform width around it, and the area of the new rectangle is one-half the area of the old garden
In order to be a walkway of uniform width it's necessary to substract of each side the same amount, for this case will be 5 ft, as shown in the Figure 2. Now the new rectangule is 20ft by 30ft.
Which is exactly one-half the area of the old garden.
This means the width of the walkway is 5ft.

Answer:
Amount left in bag one = 20kg
Amount left in bag 2 = 40 kg
Step-by-step explanation:
We are told that Two bags had 50 kilograms of sugar each.
Let first bag be x and second bag be y.
Now, we are told that After taking out 3 times as much sugar from bag one than bag two, bag one had half as much sugar left as bag two.
Thus, amount taken from bag one is;
3a and amount taken from bag two is a.
Amount left in bag 1 is;
50 - 3a while amount left in bag 2 is 50 - a.
Since bag one had half as much sugar left as bag two, then;
50 - 3a = ½(50 - a)
50 - 3a = 25 - 0.5a
50 - 25 = 3a - 0.5a
25 = 2.5a
a = 25/2.5
a = 10
Thus;
Amount left in bag 1 = 50 - 3a = 50 - 3(10) = 50 - 30 = 20 kg.
Amount left in bag 2 = 50 - a = 50 - 10 = 40 kg
