Answer:
All have same magnitude.
Step-by-step explanation:
Given that
Vector 1 = V+ (-W) = V - W
So the magnitude of vector 1, R₁
R₁ = V -W
For vector 2
Vector 2 = W - V = W - V
So the magnitude of vector 2, R₂
R₂ = V - W
For vector 3
Vector 3 = (-V) - (-W) = - V + W = W - V
So the magnitude of vector 3,
R₃ = W -V
So all have same magnitude.
Answer:
The area of the rectangular playroom is 260 feet² .
Step-by-step explanation:
Given:
The perimeter of the rectangular playroom is 72 feet and it's width is 10 feet.
Now, to find its area we need the length .
So, putting the formula of perimeter we get it's length:
Let the length be l .
Perimeter = 2( length + width)
subtracting both sides from 20:
Dividing both sides by 2:
Length is 26 feet.
And, to get the area we put the formula of finding the area:
Therefore, the area of the rectangular playroom is 260 feet² .
