120 because 60x2=120 and 10x12=120
Since a square is a rectangle, each side of the square is 50 and its area would be 2500 ft^2. A square of a quadrilateral yields the largest area.

Answer:
See below:
Step-by-step explanation:
Take the difference between y values of any two values and divide by difference in corresponding x values
for example, 1: 66-50/4-1=16
2. 36-30/8-6= 6/2=3
3. 63-56/8-7= 7/1 = 7
4. 100-78/9-7= 22/2 = 11
you can choose any two points, not just the two I used.
Answer:
-11
Step-by-step explanation:
m + n = - 2
4(m + n) = - 2(4) (multiplying both sides by 4)
4m + 4n = - 8
4m + 4n - 3 = - 8 - 3 (Subtracting 3 from both sides)
4m + 4n - 3 = - 11
