70 = 50 * x/100
x = 70/50*100 = 140

Seventh is 140% of 50.

$\frac{y-307,650}{x-9} = 850\\\\y-307,650 =850(x-9)\\\\multiply\\\\y =307,650 +850(x -9)\\\\y =307,650+850(16-9)\\\\y= 313,600$

Answer:

Approximate length of the diagonal fencing needed is 45.25 cm.

Step-by-step explanation:

Here, each side of the square shaped land = 32 ft

Now, the diagonal fencing is made in side the plot so that the land is divided into two right triangles.

<u>In the triangle:</u>

Base side of the triangle = 32 cm

Perpendicular length of the triangle = 32 cm

Let us assume the hypotenuse of the triangle = k cm

⇒The length of the diagonal in the square = k cm

by <u>PYTHAGORAS THEOREM</u> in a right angled triangle:

$(Base)^{2} + (Perpendicular)^{2} = (Hypotenuse)^{2}$

⇒ $(32)^2 + (32)^2 =k^2\\or, k^2 = 1024 + 1024 = 2048\\\implies k = \sqrt{2048} = 45.25$

or, k = 45.25 cm

Hence,the approximate length of the diagonal fencing needed to fence the square land is 45.25 cm.
