The way to find the area of a triangle is A=

if the base is 3 feet longer then the height we can write it like this B=H+3
now we can add it to our area equation
20=

20=

40=

+3H
10

=

h=3.2ft
I think it is 8.83? I am not positive but it is worth a try
P=s1+s2+s3
Move +s1 to the other side. Sign changes from +s1 to -s1
P-s1=s1-s1+s2+s3
p-s1=s2+s3
Move s2 to the other side. Sign changes from s2 to -s2
p-s1-s2=s2-s2+s3
p-s1-s2=s3
Answer: p-s1-s2=s3
