Brayden is 11 inches taller than his sister. There are 36 inches in a yard because there are 3 feet in a yard. Each foot has 12 inches. 12 times 3 is 36. Brayden is two yard tall so multiply 36 by 2 and you will find that Brayden is 72 inches tall. Now, you would subtract 61 from 72 and you would get 11. Brayden is 11 inches taller than his sister
