Question 193341: The area of a rectangle is twice the area of a square. If the length of a rectangle is 10 inches, and if the width of the rectangle is the same as the length of a side of the square, find the dimensions of both the rectangle and the square. (Hint, draw a picture of both the rectangle and the square.)
This is not from a book, it is a question from a math review that I can not figure out how to answer and the book we have does not help at all.
Thank you very much.

draw a rough sketch of rectangle(10XS) and a square (SXS)
note Ar=2As
10s=2s^2
0=2s^2-10s
0=(2s)(s-5)
2s=s, s=0,,,,,trivial answer
s-5=0,,,,s=5
check
10*5=50=2*5^2=50 ,,,,ok
