Answer:
w(w+3)= 70
Step-by-step explanation:
Hello
According to the question.
the area is 70 square inches, this means
[tex]A=length *width\\A=\ 70\ square\ inches\\70=length *width[/tex]
the length of the rectangle is 3 inch longer than the width
this means that you can take the width and add 3 inches to obtain the length or take the length and subtract 3 inch from it to obtain the width
(1)length = width +3
or
(2)length - 3 = width
now replacing (1) in the area equation
A=length*wide
A=(width +3)*wide
also
A=70 square inches
hence
(width +3)*wide=70
Let
width = w
rewriting
(w+3)*w=70
w(w+3)= 70
I hope it helps, have a great day.
