Answer:
1170 m²
Step-by-step explanation:
Parallelogram: 40 x 18 = 720
triangle: (50 x 18) / 2 = 450
total area: 720 + 450 = 1170
 
        
             
        
        
        
Answer:
point - slope form
  y - 1 = 3 (x-0)
Step-by-step explanation:
<u><em>step(i):-</em></u>
Given points are (0,1) and (2,7)
The slope of the line 
      
     
   m =3 
<u><em>Step(ii):-</em></u>
point -slope form
    y - y₁ = m(x-x₁)
Equation of the straight line passing through the point (0,1) and having slope 'm' = 3
    y - 1 = 3 (x-0)
   y -1 = 3x
  3x - y +1=0
Equation of the straight line passing through the point (0,1) and having slope 'm' = 3 is 3x -y +1=0
