It’s the 2nd answer to the right
I don't think so because they're different things!
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
1.5 and 2
2.The length is 16 and the width is 18
3.sorry can't help you
4.His grandson is 18 and Ganesh is 54.
Can't help in 5th question.Sorry!
3000cm because if you look at the variables there is no more letter m's than anything so if you cancel out and see what is equal to 30 then you get 3000cm!!!!!
