area triangle:
(1.7m×2m)×2
= 1.7m²
-> 2 triangles so: 1.7m²×2= 3.4m²
area rectangles(walls):
2m×3m
= 6m²
-> 2 walls so: 6m²×2=12m²
area bottom rectangle:
3m×2m=6m²
-> total area:
6m²+12m²+3.4m²= 21.4m²

Ok so for slope it's difference in y dividing by the difference of x. The difference of y is 10 - 6 which is 4, and the change in x is 5 - (-3) which is 8. Dividing 4 by 8 gets us 1/2. So the slope is 1/2. Slope intercept form would be y = mx + b, and the slope is 1/2 so it'd be y = (1/2)x + b. Plug in a point and you get b = 15/2. So the final slope intercept form would be y = (1/2)x + 15/2. For point slope form just put in a point and slope and you get y - 6 = (1/2) × (x + 3). Standard form would have to be arranged from slope intercept. So multiplying 2 to the slope intercept form we get 2y = x + 15. Subtracting x we get -x + 2y = 15. In standard form we don't want x to be negative so just multiply by negative one and we get x - 2y = -15.
