If the lengths of two diagonals of a rhombus are 12 cm and 16 cm , then the length of each side of the rhombus are
Answers
Step-by-step explanation:
as we know that area of a rhombus can be written as = D1 × D2/2
also we know that diagonals are 12 and 16
so
=> 12×16/2 = 96 cm²
now > area is 96 cm² but it is also clear that diagonals of rhombus intersect each other at mid point
therefore 4 triangle will be formed
which has two sides of leghth 6 and 8
(6and 8 bcoz diagonals meets at mid point)
now area of a triangle = 96 /4 = 24
therefore third side of triangle will be=>
√6²+4² = third side
= √36+16 =
Answer : 10 cm
EXPLANATION :
diagonals divide rhombus into 4 equal right angaled triangles .
whose perpendicular = 12÷ 2= 6cm
and base = 16÷2 = 8cm
and the diagnoal is the side of rhombus
h = ( 6*2 + 8*2)*1/2
(36 + 64)*1/2
100*1/2 = 10cm
