* As we know that in rhombus all sides are equal
_ let's take a rhombus named ABCD ....
* The diagonal AC divides the rhombus ABCD into two equal triangles
* for triangle ABC we have ,
s = 26 + 26 + 48 ÷ 2 = 50 cm
* area of triangle = ✓s (s - a) (s - b) (s - c)
= ✓50 * 24 * 24 * 2
= 240 cm^2
* so the area is 2 * area of triangle ABC
= 2 * 240
= 480 cm^2
