Question

find the diagonal of a rectangle whose length is 12 cm and breadth is 5 cm​

Answer 1

Answer:

the diagonal of rectangle is 13 cm

Answer 2

Answer:

13 cm

Step-by-step explanation:

If you make the diagonal, the rectangle becomes into two triangles. Thus using the Pythegoras Theorum which is used to find the length of a hypotenuse (a² + b² = c², where a and be are the lengths of the sides adjacent to the right angle and c is the length of the hypotenuse).

So, you get:

12² + 5² = c²

144 + 25 = c²

c² = 169

c = √169

c = 13 cm
