Question

find the other diaognal

Answer 1

let the length of unknown diagonal be x
we know that
area of rhombus=1/2*diagonal1*diagonal2
240=1/2*16*x
240=8*x
240/8=x
30=x
therefore the length of the other diagonal is 30cm.

Answer 2

area of rhombus=1/2*diagonal1*diagonal2
240=1/2*16*d2
240=8*d2
240/8=d2
30=d2
therefore the other diagonal is 30cm
