Answer:
W = (P - 2L)/2 = (28- 2*8)/2 = 6
Where W is the width, P is the perimeter and L is the length of the garden.
Step-by-step explanation:
Since the equations are not given, i will try to come up with the similar equation than the ne that was the correct option in this exercise.
You can obtain the perimeter of a rectangle by summing the length of its four sides. Thus, the perimeter of the garden, lets call it P, is 2W + 2L, where W denotes the width and L the length. Since Nancy knows the perimeter, in order to calculate the width she can substract from it 2L (which is also known), and divide by 2 to obtain W, thus
W = (P - 2L)/2
If we reemplace P by 28 and L by 8, we obtain
W = (28-8*2)/2 = (28-16)/2 ) = 12/2 = 6.
