Question

find the area of a rhombus whose side is 20cm and one of its diagonals is 32cm pls do step by step ​

Answer 1

Step-by-step explanation:

Rhombus

Solve for area

A=384cm²

Answer 2

Answer:

=384$cm^{2}$

Step-by-step explanation:

There are other methods to solve this but this  is the only way I know so I'm going with this

Rhombus all sides are equal

sides= 20cm    diagonal = 32cm

using herons formula we can find area of half of rhombus =

20+20+32/2= 36

$\sqrt{36(36-20)(36-20)(36-32)}$

=$\sqrt{36*16*16*4}$

= $\sqrt{3*3*4 *16* 16* 4}$

= 3* 4* 16

=192*2

=384$cm^{2}$
