Question

if the diagonals of a rhombus are 12 cm and 16 cm find its perimeter

Answer 1

hey
______

rhombus - parallelogram whose all sides are equal

properties
__________

diagonals bisect each other at 90°

by phythagoras theorem

(hypotenuse)^2 =( base )^2+ (other side )^2

(CD)^2 =( OC)^2 + (OD)^2
(CD)^2 = (8)^2 +( 6)^2
(CD)^2 = 64 + 36
CD = √100
CD = 10 cm

perimeter = 4*side
perimeter = 4*10 = 40 cm

hope helped
