a=side of rectangle=side of triangle=12; b=other side of rectangle=leg of triangle; c=diagonal=hypotenuse of triangle=15
a%5E2%2Bb%5E2=c%5E2
b%5E2=c%5E2-a%5E2
b=sqrt%28c%5E2-a%5E2%29
b=sqrt%2815%5E2-12%5E2%29
b=sqrt%28225-144%29
b=sqrt%2881%29
b=9 ANSWER: The length of the other side of the rectangle is 9.
