The area of a rectangle is obtained through the equation,
A = L x W
The width of the yard is 4 ft less than the length and may be expressed as L - 4. Length may be solved through the following steps,
A = (L)(L-4) ; 96 = L(L - 4) ; L = 12 ft
The length and width are 12 ft and 8 ft, respectively. Perimeter may be solved through the equation,
P = 2 x (L + W)
Substituting the values of L and W
P = 2 x ( 12 ft + 8 ft) = 40 ft
Therefore, the perimeter of the yard is 40 ft.
Spruce tail because if you round it from the number 8 it will turn the 4 into a 5 turning it into 10.5, which is what you need

Step-by-step explanation:
Quotient of factorials:
we are given
we can multiply top and bottom term by 21!
we can write as
As a permutation:
we know permutation formula
now, we can compare and find 'n' and 'r'
we can plug back n=25
so, we can write
Answer:
x, y. and 40 are the angles of a triangle.
x+y+40=180
x+y=140
difference between x and y is 30.
x−y=30 (2)
2x=170
⇒x=85
Substitute this value n equation (2), we get
85−y=30
⇒y=85−30
⇒y=55
angles of a triangle are x=85, y=55 and 40.
