Answer:
a technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. we can write the statement that f is a function from x to y using the function notation F:X~F
P=2(l+w)
190=2[(2l+5)+l)
190=4l+10+2l
190=6l+10
180=6l
l=30
190=2(30+w)
190=60+2w
130=2w
w=65
