Question

is it possible to design a rectangular Park of parameter 80 and area 400 m square if so find its length and breadth​

Answer 1

Answer:

answer you get is :l=20,b=20

Step-by-step explanation:

perimeter of rectangle= l+b+l+b

area of rectangle=l*b

hence, 2l+2b=80.....(1)

l*b=400

b=400/l(substitute this in equation 1)

you get a quadratic equation solve it

from this you get answer: l=20,b=20...so can see that both sides are equal only square park can be formed....hence rectangle park cannot be formed.
