Question

is it possible to design a rectangular park of perimeter 120m and area 900 m so find its length and breadth​

Answer 1

Answer:

yes it is possible l=30m b=30m

Step-by-step explanation:

let x=length y=breadth

2(x+y)=120

x+y=60

x=60-y eq 1

xy=900

(60-y)y=900 from eq 1

60y-y2=900

y2-60y+900=0

y2-30y-30y+900=0

y(y-30)+30(y-30)=0

(y-30)(y+30)

y=30,-30(not possible)

x=60-30=30 from eq 1

Answer 2

Answer:

yes it is possible

l =30 b=30

Step-by-step explanation:

put the value of b in the equation of l
