Given = sides of rhombus =12 Cm
diagonal = 16 cm
prove = to find area of rhombus
proof = area of triangle made my diagonal
Using herons formula -
Semi perimeter = 12+12+16/2
=40/2
s=20
area of triangle = √s(s-a) +(s-b) +(s-c)
√20(20-12)+(20-12)+(20-16)
√20+8+8+4
=1144.86cm sq.
area of whole rhombus = 2(1144.86)
=2289.72cm sq. (approx)

arpitrai45222222: cube not ❌ square
jatin2186: cube the area always in sq
jatin2186: if we have to find volume then we use cube
arpitrai45222222: but the ans is wrong
jatin2186: may be but I have tied my best
jatin2186: you can search this question on Google
arpitrai45222222: yeah. thnks for that
