Question

I am the fencing around a rectangler lion exhibit at a zoo the lions have 1000 m? to roam iside rectangler area that is 15 m longer than it is wide if I were to unwind and make make myself straight how long would I be

Answer 1

Answer:

130m

Explanation:

So your whole area would be 1000m^2

Long as: 15 + x

Wide as : x

We know x(x+15)=1000

x^2+15x-1000=0

Delta: 225+4000=4225

x=-15+-65/2

x= 25 and x=-40

As it is a measurement, we discard the negative measurement.

Now it is 25m wide and 40 long.

Multiply by two each to use both sides:

50+80= 130m

Hope you get it!
