How do I use the length and width given to find the perimeter of the rectangle? length: x^2+3x-1
width: 2x+3

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 )

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

i don't think there is enough
