Question

Please answer the problem above

Answer 1

Answer:

Step-by-step explanation:

Length of rectangle = 12 cm

Width of the rectangle = 6 cm

Area of the rectangle = 12 × 6

                                     = 72 cm²

Area of two semicircles = $2(\frac{1}{2}\pi r^2 )$

                                       = πr²

Here, r = radius of the semicircle

From the picture given,

Radius = $\frac{6}{2}$

           = 3 cm

Area of two semicircles = π(3)²

                                        = 9π

                                        = 28.27 cm²

Area of the entire composite figure = Area of the rectangle + Area of two semicircles

= 72 + 28.27

= 100.27 cm²
