Question

Find the length of the other side of rectangle ,if one side is 12cm and the hypotenuse is 13cm

Answer 1

Answer:

The length of the other side=5cm

Step-by-step explanation:

a^2+b^2=c^2

=> c^2-b^2=a^2

Here a is not known, b=12, c=13

=> 13^2-12^2=a^2

=> 169-144=a^2

=> 25=a^2

=> a=$\sqrt{25}$

=> a=5cm
