Question

each side of a rhombus is 61 cm and one diagonal is 22 CM now find length of other diagonal and area of Rhombus give its
Solution

Answer 1

other diagonal will be of lenght

$\sqrt{(61 {)}^{2} - \: ( \frac{22 {}^{2} }{2 {}^{2}) } } = diagonal$
it is bcoz diagonal intersect at perpendicular
diagonal will be
$= \sqrt{3600} \\ = 60cm$
and as we know area of rhombus

$= \frac{1}{2} \times first \: diagonal \times second \: diagonal$
=1/2 ×60 × 22
= 660 cm^2
this will be ur answer
