Answer:
Let's see...
Step-by-step explanation:
*Note: we can't find the exact area of the shaded figure right off the bat, we have to find the area of a bigger figure and divide it by 2.
<h3>The coordinates of the bigger figure:</h3>
A = (0,0)
B' = (0,4)
C = (5,4)
D' = (5,0)
Note: the little [ ' ] next to the B and D indicate that it is not the same coordinate as B and D, just that those points would be the same as point B and D.
<h3>That being said, what is the area of the bigger figure?</h3>
A = l * w
A = 4 * 5
A = 20 units²
<h3>Now, divide the Area by 2:</h3>
A = 20 ÷ 2
<em>A = 10 units²</em>
I hope this helps!

The answer is show that the slope of line SQ is 1 and the slope of line PR is -1.
Suppose a square has the following coordinates (0,0), (a, 0), (0, a), and (a,a).
The diagonals are distinct by (0,0) to (a,a) and (a,0) to (0,a)
The slope from (0,0) to (a,a) = (a - 0)/(a - 0) = a/a = 1 The slope from (a,0) to (0,a) = (0 - a)/(a - 0) = -a/a = -1
Two lines are thought to be perpendicular when their slopes are negative reverses of each other. In math, m2 = -1/m1
1 = -1/-1, thus these two lines, the diagonals of the square, are perpendicular.
