Area of 1,2, and 3?!??!

Step-by-step explanation:

1 = (20 x 70) + (70 x 20) = 1400 x 2 = 2800 squared meters

2 = 9.18 x 2 = 18.36 + 9.72 = 28.08 squared centimeters

3 = 9 x 4 = 36 + 6 + 3 = 45 squared units

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
