Quandaries & Queries

Question from Hannah, a student:

How do you find the area of a semi circle when no measurement is given?
The question is find the area of the garden which is semi circular.
The measurements are 24m and 26m and the semi circle's height is 10m!

Hi Hannah,

I'm confused. You say there is no measurement and then you include three measurements. Is this the diagram?

Hannah,

Your original question didn't mention a triangle. Can you send us a diagram?
