A picture frame has dimension 80m by 60m. Find the length of the diagonal of it.
Given, length of picture frame = 80 cm
and breadth of picture frame = 60 cm
Now, length of the diagonal of picture frame = √{(length)2 + (breath)2 }
= √{(80)2 + (60)2 }
= √{6400 + 3600 }
= √(10000)
= 100 cm
So, the length of the diagonal of picture frame = 100 cm
