Find out the what is the perimeter of the rectangle .
To prove
Now as shown in the figure.
Name the coordinates as.
A(−3, 4) ,B (7, 2) , C(6, −3) , and D(−4, −1) .
In rectangle opposite sides are equal.
Thus
AB = DC
AD = BC
Formula

Now the points A(−3, 4) and B(7, 2)





Thus

Now the points
A (−3, 4) , D (−4, −1)




Thus
Formula
Perimeter of rectangle = 2 (Length + Breadth)
Here






Perimeter of a rectangle = 30.6 units.
Therefore the perimeter of a rectangle is 30.6 units.
2 - 2 x 3 + 3
= 2 - 6 + 3
= -4 + 3
= -1
Answer:
(6,-4)
Step-by-step explanation:
-3x-9y = 18 (equation 1)
4x+3y = 12 (equation 2)
multiply equation 2 by 3, and add it to equation 2
-3x-9y = 18
12x+9y = 36
-----------------
X's cancel out
9x = 54
Divide both sides by 9
x = 6
Plug in 6 for x in any of the original equations
(Plugging into Equation 2)
4(6)+3y = 12 Multiply 4(6)
24+3y = 12 Subtract 24 from both sides
3y = -12 Divide 3 on both sides
y = -4
Therefore the solution is (6,-4).
