Question 948167
Read and transcribe the description exactly into equations.
w, width
L, length
p, perimeter
-
p=1040
L=w+200


You are starting with a system
{{{system(L=w+200,2w+2L=p)}}}
two equations in the two unknowns w and L.  You already know p.



You want to be able to find w and L.  What can you determine?
{{{2w+2L=p}}}
{{{2w+2(w+200)=p}}}
What next?
