What does your diagram look like?

How will you be able to use Pythagoras?
3. If you provided a diagram, it would be easier for us to help out
4. An equilateral triangle is made if you join the 3 circles' radius. Split the triangle in half to get 2 right-angled triangles and then use trig as you know that angles in an equilateral triangle are 60 degrees. That will give you the height between the circle. Add the 2 radii to the length you worked out to give you the height of the rectangle. And then just find the area
