Let's say each side of the square =
If we put 7 squares in a row to make the rectangle,
length of the rectangle =
Area of a rectangle = length multiplied by width
Area of rectangle = multiplied by
=
We are also told that the total area = 567
So
Now solve for .
Divide both sides by 7.
Then square root both sides to find
= 9

Step-by-step explanation:
Given:
The beginning of the left edge of the stencil falls at (2, −1).
A point, say Q on the stencil is at (4, 1).
Point Q divides the stencil into the ratio 1:4.
We are required to find the end of the stencil.
Mathematically, Point Q divides the stencil internally in the ratio 1:4.
For internal division of a line with beginning point and end point
in the ratio m:n, we use the formula
,
, Q(x,y)=(4,1), m:n=1:4
Therefore:
The correct option is A.
