Some really crazy number, so what you have to do is go and get the calculator app and type it in then you press the square root button and then you hit enter or the = sign.
Answer:
the fence needed to enclose the garden = 140 ft.
Step-by-step explanation:
given:
rectangular garden is 25 ft. by 45 ft.
find:
how many feet of fence are needed to enclose it?
use the perimeter of a rectangle formula = 2L + 2W
let L = 45 ft.
let W = 25 ft.
plugin values into the formula
P = 2L + 2W
P = 2(45) + 2(25)
P = 90 + 50
P = 140 ft.
therefore,
the fence needed to enclose the garden = 140 ft.
<span>The perimeter of the area is the length of the fence.
Perimeter = x + y + y. This can be simplified to
Perimeter = x + 2y. You're told that the rancher has 100 m of fence, so the perimeter is 100 m:
100 = x + 2y (1)
The area of a rectangle is given by the formula A = length * width. The length in this case is x, and the width is y.
So, A = xy.
Solve equation (1) for y. Once you find the expression to which y equals, plug that for y into A = xy.
100 = x + 2y. Solve for y by subtracting both sides by x:
100 - x = 2y. Divide both sides by 2:
(100 - x)/2 = y
Substitute (100 - x)/2 for y into A = xy:
A = x[(100 - x)/2]
A = [x(100 - x)]/2
You can rewrite this as (100x - x²)/2 or 50x - (x²/2) or 50x - (1/2x²).

Answer:
Slope "m" = (y2 – y1)/(x2 – x1).
Step-by-step explanation:
The slope formula is m=(y2-y1)/(x2-x1) or rise over run
well if the area of rectangle is 5x² ... and x² has a value here ... so the coefficient 5 means that the answer is 5 × x²....
in other words ... we just have to multiply the value of x² with 5
