Answer:
Since the measurement can't be negative the correct answer for this case would be
Step-by-step explanation:
Let's assume that the figure attached illustrate the situation.
For this case the we know that the original area given by:
And we know that the initial area is a half of the entire area in red , so then:
And we know that the area for a rectangular pieces is the length multiplied by the width so we have this:
We multiply both terms using algebra and the distributive property and we got:
And we can rewrite the expression like this:
And we can solve this using the quadratic formula given by:
Where if we replace we got:
And the two possible solutions are then:
Since the measurement can't be negative the correct answer for this case would be
Answer:
Step-by-step explanation:
Given
Required
Find Y
To do this, we make use of the mid-point formula
i.e.
WX and ZY are the diagonals of the parallelogram.
The mid-point of WX is:
The mid-point of ZY is:
Equate both values of M
Multiply both sides by 2
By comparison:
Hence:
