Question

Find the area of the irregular figure (use 3. 14 for pi). Show your work. Round to the nearest tenth.

Answer 1

Based on the information given, the value of the area of the irregular figure will be 13.7 ft².

How to calculate the area.

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
