Question 33350
If I've got this correctly, then you have a triangular corner removed from a square area, This area that is removed is then transformed into two equal-sized strips that are attached to the two 48m-long sides of the square.
If that is so then, the area of each strip is 112.5/2 = 56.25 mē.
Since the length of a strip is 48 m then the width is 56.25/40 = 1.40625 m.
