Question 135653
The length of a rectangle is 3 in longer that twice its width w : Write a polynomial expression in standard form in terms of w for the area of the rectangle.Find the area of the rectangle for w=10 
------------------------------------
Let the width be "w"
Then the lengthis"w+3"
----------------------------
Area = w(w+3)
A(10) = 10(10+3)
A(10) = 10(13) = 130 sq.in.
