Answer:
x = -30
y = -20
Step-by-step explanation:
x - 12y = 210..... (I)
x - 6y = 90..... (II)
Subtract equation (II) from (I)
- 12y - (-6y) = 210 - 90
-12y + 6y = 120
-6y = 120
Divide through by -6y
Therefore, y = -20
Substitute y = -20 in equation (II)
x -6 (-20) = 90
x + 120 = 90
x = 90 - 120
x = -30

Answer:
Step-by-step explanation:
The width is 220 feet.
100 yards = 300 feet
300 x 2 = 600
1040-600 = 440
Since you have 2 equal sides representing the width 440/2 = 220
Check it by adding all sides to get perimeter:
220+220+300+300= 1040
The answer would be 66.5 sq :)!
