Answer:

1044 cm²

Explanation:

Split the shape up into two

Area of shape A:

Area = length × width

To calculate the width = 46 - 21 = 25 cm

Area = 30 cm × 25 cm = 750cm²

Area of shape B

Area = length × width

Area = 14 cm × 21 cm = 294 cm²

Add up both of the areas:

750 cm² + 294 cm² = 1044 cm²
