Question

Is it
possible to design a rectangular park
perimeter 80 postm and area 400 m² ? If so find ,
in the length and breadth​

Answer 1

Answer:

Bhai possible to sab hota hai but is question me possible nahi hai

Answer 2

Answer: Yes , it is possible to design a rectangular(square) field with given measurements where l = b = 20m .

Step-by-step explanation:

A/Q , Area of the park = 400 m²

Perimeter  = 80m

We know that perimeter of a rectangle = 2(l+b)

:. 2(l+b) = 80

l+b = 40

l= 40-b----(1)

We know that area of a rectangle =lb

:.lb = 400

(40-b)b = 400      [using (1)]

40b - b² - 400 = 0

b²-40b+400 = 0

(b²-20b)+(-20b +400) = 0

b(b-20)-20(b-20) = 0

(b-20)(b-20) = 0

:. b = 20 m

Substituting 'b' in (1)

l = 40 - 20

:. l =20 m

Thus yes , it is possible to design a rectangular(square) field with given measurements where l = b = 20m .

I hope this helps you. Have a great day! :D
