Answer 2

Answer:

hey mate here is your answer...

Step-by-step explanation:

Let the length and breadth of rectangular field is x and y respt.

Then area =xy=150.................(1)

And perimeter of rectangular field =2x+2y=50

Or x+y=25--------------------------------------(2)

Or x=25-y Put in (1)

So y(25-y)=150

25y−y

2

=150⇒y

2

−25y+150=0⇒y

2

−15y−10y+150=0⇒y(y−15)−10(y−15)=0⇒(y−10)(y−15)

So y=10 or y=15

Or x=25-15=10 or x=25-10=15

Then its dimensions are 10 ,15
