It's not a trapezium; it's a kite.

Find the area of triangle OAT and multiply by 2. (Then subtract the area of the sector of the circle.)

hi Maou-Sama

Welcome to the forum.

There are many on-line sites that will let you store an image and get the bbCode to embed in your post. I use imgur.

Here's the latest one that I did:
