If the radius of the circle that is inscribed in a rhombus of side 25 cm is 12 cm, what is the area (in cm^2) of the rhombus ?
1)300
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 ?

this question is not understandable.
rohmbus has equal sides.
why they have given two different length
2006-08-01 05:23:01 · update #1
Area = a * h
A = 25 * 12
A = 300
ANS : 300cm^2

helped me see it more clearly.
If you notice, the radius forms the height, if you were to move the radius over to the left until it goes from the vertex to the bottom side.

If you lay the rhombus on a side, you can see that the height of the rhombus is the same as the diameter of the circle = 24.
Then you can use the parallelogram formula (which a rhombus is a special case, to find the area. base * height = 600

It is 2) 600.
Expl: (4*1/2*25/2*12)
