Use the property of a right triangle
$$
d^2 = w^2+  l^2
$$

anonymous · Answer

$$
d^2 = 200^2 + 130^2
$$

anonymous · Answer

It should be easy now.

anonymous · Answer

The angles of a rectangle are each of value 90 deg. So , you can proceed as eliassaab showed and find out the value of the diagonal from it.

anonymous · Answer

$$
d^2 = 200^2 + 130^2=56900\
d= \sqrt{56900}\approx 238.537

$$
