ABCDEF = 36cm² 4x² - 10x = 36cm² 4(4.5²) - 10(4.5) = 81 - 45 = 36cm² x = 4.5cm AB = x AB = 4.5cm
still no marks?? any idea? ik mathswatch can be useless sometimes but im OCD about getting 100% lmao
Answer is right but its mathswatch formatting. ABC is a triangle. It may be it wants some of the -b+/-sqrt() formatting to show that the calculation is correct, but (thankfully) I'm not a mathswatch expert so I'll bow out.

Yes I'm aware of that, but I didn't know how to define the rectangles when there was no letter to represent the extra angles and its mathswatch so I couldn't add one.
I'll have a go with that format and swap everything around a little and if it doesnt work then email my teacher, thank you for the help, and sorry about the late reply🙂
