<h2>Solution:.</h2>
Let the ceilings be <em>a</em><em> </em><em>&</em><em> </em><em>b</em>
and the distance from one corner of the ceiling to the opposite be <em>c</em>
<em>then </em><em>using</em><em> </em><em>Pythagoras</em><em> theorem</em>

hence ,c .°. the distance from one corner of the ceiling to the opposite is<em> </em><em>2</em><em>0</em>
(13/4)*3 = 39/4 ft
I believe that's the answer
This is how you write 5.24 in expanded form 5+0.2+0.04
8/9 / 4/9
=(8/9)*(9/4) Multiply by second reciprocal
=(2/1)*(1/1) Cross reduce
=2 Multiply
