Question

The length of the diagonals of a rhombus are 16 cm and 12 cm respectively. The perimeter of the rhombus in cm is
​

Answer 1

Answer:

the perimeter is 40 cm

now please follow me and thanks me

Answer 2

Answer:

name the rohombus ABCD

AC is 16 cm and BD is 12 cm

diagonals of rohombus bisect ech other into two equal parts

Name the central point where diagonal bisect be O

in triangle ABO

2 sides are 6 cm and 8 cm respectively (12/2 and 16/2)

using phthagoras theorem

$(Hyp)^{2}$ = $(base)^{2}$ + $(perp)^{2}$

$(not given)^{2}$ = $12^{2}$ +  $16^{2}$

hyp = $\sqrt{144 +256}$

Hyp = $\sqrt{400}$

hyp = 20

dimensions of every triangle in rohombus id the same

perimeter= 20 + 20+ 20+ 20=

80 $cm^{2}$
