Question

find the area of rhombus in which each side is 15 cm long and one of whose diagonal is 24cm​

Answer 1

1/2×diagonal× length

1/2×24×15

1/2×360

180

Answer 2

The formulas for area of rhombus are:

1)base×corr. height

2)1/2×diagonal1 × diagonal2

3) this one requires trignometry but one interior angle must be given

The information given doesn't satisfy any formula so the information given is insufficient.

It is also not a square as 15^2 + 15^2 isn't equal to 24^2

Hope i helped.
