Question

*Length and breadth of a rectangle are 24 cm and 18 cm. Find the length of its diagonal.*

1️⃣ 18 cm
2️⃣ 24 cm
3️⃣ 30 cm
4️⃣ 15 cm​

Answer 1

24²+18²=diagonal²

576+324=diagonal²

diagonal=√900

diagonal=30cm.

hence, option 3 is right

Answer 2

Answer:

4.) 15 cm is the correct answer

Step-by-step explanation:

Let the rhombus is ABCD, given that :

AC=24cm and BD=18cm.

Let the Diagonal of Rhombus bisect each other at right angles.

AO=OC= 12

and OB = OD =9 cm

Let ∠AOD=90°

In right ΔAOD,

AO= 12 cm and OD=9 cm

Using phythagoras theorem,

AD² = AO² + OD²

AD² = (12)² + (9)²

AD=15 cm
