Answer:
45m
Step-by-step explanation:
you have to find the diagonal by using the pitagora's theoreme.
it uses the formula [tex]\sqrt a^{2} +b^{2}[/tex] when you have to find the lenght of the longer side of a triangle with an angle of 90°. So the diagonal will be [tex]\sqrt27^{2} +36^{2}[/tex] =[tex]\sqrt729+1296[/tex] = [tex]\sqrt2025[/tex] = 45
