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
It is 36 feet
A=1/2bh
a=1/2*12*6
a=6*6
a=36feet squared
hope this helps!

The summation of negative 5 n minus 1, from n equals 3 to 12 can be
expressed as
n = 3/12
substitute the value of n to the equatio
-5n – 1
-5( 3/12 ) -1
-9/4
