Question

In a rhombus of side 10cm one diagonal is of length 16cm. Find length of the other diagonal.

Answer 1

when we join the diagonals of the rhombus, we get a right angle triangle
let, orher diagonal be d
then, according to pythagoras theorem,
10^2 = (d/2)^2 + (16/2)^2
100=d^2/4 +64
d^2 / 4 = 100-64 = 36
d ^2 = 36 × 4
d^2 =144
d = 12 cm, Ans.

Answer 2

The answer is d=12 so this is the correct ans
