The width of the rectangle become 20 cm.
According to the statement
we have to find the width of the rectangle.
So, For this purpose, we know that the
Rectangle is a parallelogram all of whose angles are right angles.
According to the information:
A rectangle has a length of 21 cm and a diagonal of 29 cm.
Here we use the this formula
d² = l² + w²
So, Substitute the values
29² = 21² + w²
841 = 441 + w²
Now, solve it then
w² = 400
Solve the square root then value becomes
w = 20 cm.
The width of the rectangle become 20 cm.
So, The width of the rectangle become 20 cm.

Answer:
The roots of equations are as m =
And n =
Step-by-step explanation:
The given quadratic equation is 2 x² + 6 x - 1 = 0
This equation is in form of a x² + b x + c = 0
Let the roots of the equation are ( m , n )
Now , sum of roots = 
And products of roots = 
So, m + n =
= - 3
And m × n = 
Or, (m - n)² = (m + n)² - 4mn
Or, (m - n)² = (-3)² - 4 (
)
Or, (m - n)² = 9 + 2 = 11
I.e m - n = 
Again m + n = - 3 And m - n = 
Solving this two equation
(m + n) + ( m - n) = - 3 + 
I.e 2 m = - 3 + 
Or, m = 
Similarly n =
Hence the roots of equations are as m =
And n =
