Question

In rhombus ABCD, AC = 30 inches and BD = 40 inches.


What is the perimeter of the rhombus?
(picture to come)

Answer 1

it's the closest I could get to a rhombus.

Answer 2

in a rhombus diagonals cut at right angles
side DA=Square root[(30/2)^2+(40/2)^2]
=square root(15^2+20^2)
=square root(225+400)
=square root625
=25
In a rhombus all sides are equal.
perimeter=4*25=100 inches
