2)600
3)625
4)576


I only know Area of rhombus = 1/2 xd1xd2

d1,d2 are length of diagonals....but it seems here i cant apply this formula....so, how do i calculate the area ?

I would like to use this fan while travelling. I have a converter for voltage (240 to 120) but nothing to convert Europe's 50 cycle (Hertz) current to 60 cycle. If the voltage is converted to 120 but the cycles are left at 50, will the fan run 17% slower? or overheat? or just not work!

I have a veggie garden that I go out and water every other day and this time today when I went out to water there were tiny neon-orange rings on the mounds and on some of the leaves, not clumped together or anything, but evenly spread out rings like a lichen or fungi, I live in semi arid central oregon and our hose water is from a river (Crooked River.) Hope all this info helps, I've looked online and can't find any photos or information on these things
