Step-by-step explanation:
how many layers of bricks are used ?
also, I assume, the thickness of bricks means actually their height when laid.
but still, I cannot answer that, as nothing indicates if there is only one layer of bricks or 2 or 3 or 4 or ...
Area=legnth times width
36 and 1/4=8 and 3/4 times width
conver to imrpoer
36 and 1/4=145/4
8 and 3/4=35/4
145/4=35/4 times x
times both sides by 4
145=35 times x
divide both sides by 35
29/7=x
4 and 1/7=x
answer is 4 and 1/7=legnth
He was thinking of 23
I’ve attached my work on how I got it....
