Question

3. If perimeter of a rhombus is 100 cm and length of one diagonal is 48 cm, what
is the area of the quadrilateral ?​

Answer 1

Side of rhombus = 100/4 = 25cm

if length of 1 diagonal is 48 other diagonal is :

25 square = 24 square + x square ( x being half of other diagonal )

hence x = 7cm

and diagonal is 14cm

Area of rhombus = d1 x d2 /2

= 14 x 48 /2

= 336 cm square
