Is it possible to design a rectangular park of perimeter 80 m and area 400 m square ? if so, find its length and breadth.

Answer»

Answer:

Hola‼.........❤✌

Let length of the rectangular PARK be x m and breadth be y m.

According to question,

perimeter = 80 m ⇒ 2(l + b) = 80 m

⇒ 2 (x + y) = 80

⇒ x + y = 40

=> y = 40-x

i.e, breadth =(40- x) m

Now, area = 400

=> l×b = 40

=> x (40-x) = 400

=> x^2 -40x +400 = 0

Here, a = 1, b = –40, c = 400

Now, D = b^2 – 4ac

 = (-40)^2 – 4(1) (400) = 1600 – 1600 = 0

Since, D=0

So, the GIVEN quadratic equation has equal roots and hence it is possible to design a rectangular park.

Now, solving the the quadratic equation x^2 - 40x +400 by quadratic formula, we get

x= -b +- √D/ 2a

= 40/2

= 20

Hence, length of the rectangular park, x = 20 m

& breath = (40-x) = 20 m

Hope it's helpful.... ☺

If A, B, C are interior angle of a triangle abc then show tan (A+B/2) =cot c/2

Answer»

Step-by-step explanation:

In A triangle ,

A + B + C = 180°[ANGLE Sum Property Of Triangle]

Divide both SIDES by 2

A + B + C/2 = 180/2

A + B/2 + C /2 = 90

A + B/2 = 90 - C/2

Taking Tan On both sides ,

Tan (A + B/2) = Tan(90 - C/2)

Tan (A +B/2) = Cot (C/2)

Hence Proved.....

Find the greatest number will dividual 615 and a 963 leaving the six in each case

Answer»

Step-by-step explanation:

The required GREATEST number be the H. C. F of ( 615 - 6 ) and ( 963 - 6 )

so we will find the H. C. F of 609 and 957

GIVEN numbers are 957 and 609 clearly 957 > 609 . Therefore it is the H. C. F of 609 and 957. The remainder at this step is zero. so the divisor at this stage I.e 87 is the H. C. F of 609 and 957

Therefore 87 is the required greatest number that will divide 615 and 963 leaving 6 in each case

Hope it will help you
