The perimeter of the room is units.
The area of the square room is = square units.
We know that the area of a square is given as the product of its sides,
Therefore the value of each side is = unit
Side of the square room is = unit
Thus the perimeter of a square is given as the 4*length of each side.
∴ Perimeter = 4* = units.
Thus the perimeter of the square room is units.

b. x² + 2x - 2,115 = 0
c. x² + 2x + 2,115 = 0
Answer:
x² + 2x - 2,115 = 0
Step-by-step explanation:
Two consecutive odd integers looks like x+2. consecutive numbers are x+1. (odd numbers skip by 2 numbers. like between 5 and 7 is 2. )
SOOOO....
Now we can start. The product of two consecutive odd integers looks like
x(x+2) and it equals 2, 115 ---> x(x+2)=2,115
solve left side: x^2 +2x = 2,115
then move 2115 to left side to have a quadratic equation (make it equal to zero)
now we have:
x^2 +2x -2,115=0
that is you answer!
Hope it helps! ;)
