Recall that a square is just a rectangle with all sides equal.
and the area of a rectangle is just length * width.
Answer:
132
Step-by-step explanation:
1. -3(2z-8d) Solve within the parenthesis.
2. 2(6)=12, 8(7)=56
3. Do the math within the parenthesis with our new integers. 12-56=-44
4. multiply both integers now. -3(-44) = 132
*a negative times a negative wil give you a positive answer.

Step-by-step explanation:
Find c if ∠PQR = 90°?
I will ASSUME you mean point P is at (3. c)
slope of PQ is (2 - c) / (9 - 3) = (2 - c) / 6
slope of QR is (11 - 2) / (3c - 9) = 9 / (3c - 9)
perpendicular lines have negative reciprocal slopes.
(2 - c) / 6 = -1(3c - 9)/9
9(2 - c) = -6(3c - 9)
18 - 9c = -18c + 54
9c = 36
c = 4
