Question

Find the area of a rhombus whose side is 6cm and altitude is 4cm. If one of the diagonal is 8cm long, find the length of the other diagonal

Answer 1

area of rhombus = altitude× side
6×4=24
area of rhombus= 1 /2 × d1×d2
$\frac{1}{2} \times 8 \times x = 24 \\ 4x = 24 \\ x = 6$
other diagonal= 6cm
area = 24cm2
