Answer: 120

Explanation:
The top part of this polygon is a triangle and the bottom is a rectangle. In this way, we can use the are of a triangle formula and the area of a rectangle formula to find the total area of the polygon.
Area of a triangle:
A = (base * height) / 2
= (6m*8m)/2
= (48m)/2
= 24

Area of a rectangle:
A = base * height
= 12m * 8m
= 96

Area of the polygon:
A = area of triangle + area of rectangle
= 24m + 96m
= 120
