Based on the information given, the value of the area of the irregular figure will be 13.7 ft².
<h3>How to calculate the area.</h3>
From the complete question, the area of a triangle will be:
= 0.5 x base x height
= 0.5 x 3.6 x 4.8
= 8.64 ft²
Area of the semicircle = 0.5πr²
Area of the semicircle = 0.5 x 3.14 x 1.8²
Area of the semicircle = 5.09 ft²
Area of the irregular figure = Area of the semicircle + Area of the triangle
= 5.09 ft² + 8.64 ft²
= 13.73ft² = 13.7 ft²
