A rectangular wooden gate has a width w w\,w and a height hhh. A metal diagonal brace of length d d\,d is attached from one corner to the opposite corner.
w=1.8w = 1.8w=1.8 m correct to the nearest cm
h=0.9h = 0.9h=0.9 m correct to the nearest cm
Calculate the lower bound for the length of the brace ddd.
