Length (l) = 45 m
Breadth (b) = 30 m
We know, perimeter of a rectangle = 2(length + breadth)
Therefore, perimeter of the rectangle
= 2(I + b)
= 2(45 + 30) m
= 2 × 75 m
= 150 m
So, the distance travelled by Rubina
= 4 × 150 m
= 600 m

Answer:

The distance travelled by Rubina is 600 m.

Hope you could get an idea from here.

Find the roots of the quadratic equation w+w²/3=0

Daniel [21]

I assume that the equation you mean is below:

$\large \boxed{w + \frac{ {w}^{2} }{3} = 0}$

To find roots for this equation, we have to get rid of the denominator. We can do by multiplying both sides by 3.

$\large{w(3) + \frac{ {w}^{2} }{3} (3) = 0(3)} \\ \large{3w + {w}^{2} = 0}$

Factor w-term out (common factor)

$\large{w(3 + w) = 0} \\ \large{w = 0 \: \: \: or \: \: \: 3 + w = 0} \\ \large{w = 0, - 3}$

Answer

The roots of quadratic equation are 0,-3
