Answer
Length of all sides of rhombus = 52 cm
Given
The lengths of the diagonals of a rhombus are 24 cm and 10 cm, respectively
To Find
Length of all its sides or simply Perimeter
How to Solve
Revise two properties of rhombus
1 . All sides of rhombus are equal
2 . Diagonals of rhombus bisect each other
___________________________
We have lengths of two diagonals . So , we can know the length of side of rhombus easily by applying Pythagoras theorem .
Solution
Find attachment for diagram
Given ,
AC = 24 cm
[ ∵ Length of 1st diagonal ]
BD = 10 cm
[ ∵ Length of 2nd diagonal ]
Now , A/c to 2nd property ,
AO = 12 cm [ ∵ half of 24 cm ]
BO = 5 cm [ ∵ half of 10 cm ]
Apply Pythagoras theorem for finding AB , Length of side of rhombus ,
⇒ AB² = AO² + BO²
⇒ AB² = (12)² + (5)²
⇒ AB² = 144 + 25
⇒ AB² = 169
⇒ AB = 13 cm
Now , AB = BC = CD = DA
[ ∵ A/c to 2nd property All sides of a rhombus are equal . ]
So ,
Perimeter of rhombus = AB + BC + CD + DA
⇒ 13 + 13 + 13 + 13
⇒ 52 cm
So , length of all sides of rhombus = perimeter = 52 cm
Answer :
Length of all sides of rhombus are = 52cm.
Given :
- Length of sides of rhombus are 24 cm and 10 cm respectively.
To find :
- Length of all sides of rhombus.
★
Length of 1st diagonal [AC] = 24 cm.
Length of 2nd diagonal [BD] = 10 cm.
According to the condition to 2nd property,
Taking half of lenghts of diagonals
AO = 12 cm
BO = 5 cm
Now, Using Pythagoras theorem (PGT) for finding
side AB if a rhombus ,
→ AB² = AO² + BO²
→ AB² = (12)² + (5)²
→ AB² = 144 + 25
→ AB² = 169
→ AB =
Now, AB = BC = CD = DA .......{ All sides of rhombus are equal} .
Length of all sides of rhombus = 13 + 13 + 13 + 13
→ 52 cm.
•°• Length of all sides of rhombus = 52 cm.
