Answer:

553.43 cm²

Explanation:

This is a composite figure, so we will need to find the area of the semicircle separately from the area of the trapezoid and then add them together in the end.

Trapezoid

A = h(b1+b2)/2

A=8cm(20cm+30cm)/2

A=8cm(50cm)/2

A=400cm²/2

A=200cm²

Semicircle

r=d/2

r=30cm/2

r=15cm

A=(πr²)/2

A=(π×(15cm)²)/2

A=(π×225cm²)/2

A=353.4291735 cm²

Total Area

A=353.4291735 cm²+200cm²

A=553.43 cm²
