Solve for x
4 12
--- = --- 4x=36 36/4=9 x=9 = PQ=9in
3 x
4 18
--- = --- 4x=54 54/4=13.5 x=13.5 QR=13.5in
3 x
4 24
--- = --- 4x=72 72/4=18 x=18 PR=18in
3 x
18+13.5+9 = 40.5
Therefore, the perimeter of ΔPQR = 40.5inches
B: (0, a)
C should have the same y value as B
D: (a,0)
C should have the same x value as D
So point C is (a,a)
Since point A is on the origin, its point is (0,0)
You use the slope formula and plug in point A and C:
m = 1
So the value that belongs in the green box is 1
Pretty sure it is 3 units
