Question

Find the length of the longest straight line which can be drawn on a rectangular board which is 2.2m by 1.2m

Answer 1

Answer:

The longest straight line will be the diagonal of the rectangle

Which could be found by using pythagoras property

Let the length of the diagonal be x

x^2 = 2.2^2 + 1.2^2

x^2 = 4.84 + 1.44

x^2 = 6.28

x = √6.38

Hence the length of the diagonal is √6.38 which is the longest straight line
