To find the area of an irregular polygon you must first separate the shape into regular polygons, or plane shapes. Then, find the area of each of those polygons using the regular polygon area formula.
A₁ = LW
A₁ = (13.0mm)(4.0mm)
A₁ = 52mm²
A₂ = LW
A₂ = (10.0mm)(4.0mm)
A₂ = 40mm²
The last step is to add all those areas together to get the total area of the irregular polygon.
Total Area of the given CompositeShape:
A = A₁ + A₂
A = 52mm² + 40mm²
A = 92mm²
Therefore, the total area of the composite shape is 92mm²

ANSWER:
===========================================
FORMULA USED:
SOLUTION:
A₁ = LW
A₁ = (13.0mm)(4.0mm)
A₁ = 52mm²
A₂ = LW
A₂ = (10.0mm)(4.0mm)
A₂ = 40mm²
Total Area of the given Composite Shape:
A = A₁ + A₂
A = 52mm² + 40mm²
A = 92mm²
Therefore, the total area of the composite shape is 92mm²
