A rectangle's diagonal is a hypotenuse of a right triangle.
Therefore given a width (a)which is 12 in and a hypotenuse (c) which is 13 in, the length (b) will be:
b%5E2=c%5E2-a%5E2
b%5E2=%2813%29%5E2-%2812%29%5E2
b%5E2=169-144
b%5E2=25
b=5
The area:
A=%28ab%29%2F2
A=%2812%2A5%29%2F2
A=30in%5E2
Hope that helps!
