reCaptcha width issue

Good day,

This is our website http://dialysisschoolofsd.com/. When you scroll down to Contact Us and see the form you will notice that the reCaptcha was not full width like the other fields I have there. I would like to ask what should I do to make it full width so that they will be even is size and height.

Always looking forward with all your help regarding my issue. Thanks in advance.

Regards,
Ivan
