Answer:

230cm²

Explanation:

The shape can be split into two shapes horizontally: a triangle and a rectangle.

Area of the rectangle

The area of a rectangle = length × width

In this case, the length is 20cm and the width is 7cm. 20 × 7 = 140cm²

Area of the triangle

The area of a triangle = 1/2 × base × height

In this case, the base is 20cm and the height is 9cm (16cm - 7cm). 1/2 × 20 × 9 = 90cm²

Area of the shape

To find the area of the total shape, we can add 140cm² and 90cm² to get 230cm².

Hope this helps!
