Area of the rectangular yard = 96 square feet
Let us assume the length of the yard = x feet
Width of the yard = x - 4 feet
Then
Area of the yard = length * width
96 = x(x - 4)
96 = x^2 - 4x
x^2 - 4x - 96 = 0
x^2 - 12x + 8x - 96 = 0
x(x - 12) +8(x - 12) = 0
(x - 12)(x + 8) = 0
As the value of length cannot be negative so
x - 12 = 0
x = 12
So
Length of the yard = 12 feet
Width of the yard = x - 4 feet
= 12 - 4 feet
= 8 feet
Then
Perimeter of the yard = 2 (length + width)
= 2(12 + 8)
= 2 * 20 feet
= 40 feet.
So the perimeter of the yard is 40 feet.

Answer:
12
Step-by-step explanation:
We can use the Pythagorean theorem to find the answer
The lengths in the problem form a right triangle with a hypotenuse of 20ft and legs of 16ft and the horizantal distance
400-256 = 144
✓144 = 12
Answer:
correct option is option A.
Step-by-step explanation:
July sales forecast = 6000 units
cost of one unit which is going to be sold = $10.50 per unit
total sale in the month of July is equal to
= 6000 × $10.50
= $63,000
hence the total sale in the month of July comes out to be = $63,000
so, the correct option is option A.
