Answer 2

Since,a rhombus is also a kind of a parallelogram.

Formula of area of rhombus =Base×Altitude

Putting values, we have

Area of rhombus =8×6=48

Since, Area of rhombus is 48 cm².

Also,formula for area of rhombus =$\frac{1}{2}×d_1d_2$

Given,Length of one diagonal =$d_1$=12

Let length of other diagonal =$d_2$

After substituting the values, we get

$48=\frac{1}{2}×12×d_2$

$48=6×d_2$

$6×d_2=48$

$d_2=\frac{48}{6}$

$d_2=8$

Hence, length of other diagonal is 8 cm.
