Question

the sides of a rectangle are 5 cm and 12 cm long. what is the length of its diagonals?

Answer 1

Explanation:

144-25=119

√119 cm is your answer (by Pythagoras theorem )

Answer 2

Answer: 13 cm

Explanation: Let A be 5cm

Let B be 12 cm

Therefore, A^2+B^2=C^2(According to Pythagoras Theorem)

So, (5)^2+(12)^2=25+144=169

Therefore, C^2=169

Therefore, C=13 cm
