If it's a perfectly rectangle frame with W = 50 cm & L = 90 cm

So the right diagonal should be √ (50² + 90²) = √10600 = 102.96 cm

as per the calculation the diagonal should have a length of 102.96 cm, but the boss found 100 cm, that means their should be a frame which diagonal equal to 100 cm, short by 2.96 cm, that means short by 2.96/2 = 1.48 cm from the bottom & 1.48 cm from the top (same as well as for the 2nd diagonal)

In this case the boss should be happy
