Step-by-step explanation:
follow the PEMDAS method then see if the 2 equation equal each other after plugging in the x.
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 the answer might be 72
Depending on interest it could be doubled if not more.
