Answer:
Slope = 0
Step-by-step explanation:
Equation: y = 5
Since the graph would show a horizontal line (passing through 5) the slope would be zero
you can just split the figure in 2 separate figures and them add the areas:
area rec. 1:
3m×3m= 9m²
area rec. 2:
3m× (2m+3m)
= 3m×5m
=15m²
total area:
9m²+15m²= 24m²
