Answer 1

• Adjacent sides of a rectangle are 12 cm and 5 cm then the length of its diagonal is ______cm. As we know that, Adjacent sides of a rectangle are length and breadth . Angles between adjacent sides of a rectangle is equal to 90°

Answer 2

Answer:

Length of diagonal is 13cm.

Step-by-step explanation:

Good question. To answer I will use the Pythagoras theorem.

a² + b² = c²

Here, given a = 12 and b = 5.

(12)² + (5)² = 144 + 25 = 169

169 = c²

✓169 = ✓c² (Rooting both the sides to remove the ² from C)

13 = C

Thus the length of diagonal is 13 cm.
