Answer: 127.63 cm²

Step-by-step explanation:

We are given a composite figure made up of a rectangle and two semi-circles. Together, this gives us a rectangle and a circle. We will find the area of the complete figure.

Area of a rectangle plus the area of a circle:

        A = LW + πr²

Substitute given values:

➜ r = W/2 = 5.9/2 = 2.95

        A = (17 cm)(5.9 cm) + (3.14)(2.95 cm)²

Square and multiply:

        A = 100.3 cm² + (3.14)(8.7025 cm²)

Multiply:

        A = 100.3 cm² + 27.32585 cm²

Add:

        A = 127.62585 cm²

Round to the nearest hundredth:

        A ≈ 127.63 cm²
