Find area of rhombus side is 5 cm and altitude is 4.8 if one diagonal is 8 cm find length of other diagonal

Given that,

side =5 cm

altitude = 4.8

one diagonal (d1)= 8 cm

We know that

Area of a rhombus = × altitude.

= 5 × 4.8

Area of a rhombus = 24 cm2……………………..(1)

Let the other diagonal be d2

Area of a rhombus = 1/2.(d1×d2).

= 1/2.( 8×d2).

Area of a rhombus = 4×d2………………………(2)

From eqn. (1) and (2).

4×d2 = 24 .

d2 = 24/4. = 6 cm.

Hence length of other diagonal (d2)= 6cm

and area of rhombus = 24 cm2
