Answer:
A=400, L=2W, L*W=A so, L*W=400, so, 400=2W*W or 200=W*W or 200=,
= W, L=2(
) and W=
, W=14.14 and L=28.28

Answer:
Step-by-step explanation:
We would multiply the fraction by its conjugate
( A conjugate is a expression that has the same integer or number values but have different signs) for example
and
ARE Conjugates.
The conjugate of
is
So this means we will multiply the expression by 1 plus sqr root of 5 on the numerator and denominator.
Our new numerator will be
We can apply the difference of squares for the denominator.
So our denominator will be
So our rationalized fraction will be
