The length, width and diagonal of the rectangle form a right triangle. The diagonal is the hypotenuse (longest side of the triangle). Use the Pythagorean Theorem:
Let a = 24
Let b = 10
Let c = diagonal
a%5E2+%2B+b%5E2+=+c%5E2
24%5E2+%2B+10%5E2+=+c%5E2
576+%2B+100+=+c%5E2
676+=+c%5E2
c+=+26
The diagonal is 26 cm.
