Answer:
c) 56 m²
Step-by-step explanation:
Area of the figure = area of triangle + area of rectangle
Rectangle:
length = 8 m
Width = 5 m
Area = length * width
= 8 *5
= 40 m²
Triangle:
base (b)= 4 m
height (h) = 8 m
[tex]Area=\frac{1}{2}bh\\\\ =\frac{1}{2}*4*8\\[/tex]
= 2* 8
= 16 m²
Area of the figure = 40 + 16
= 56 m²
