Question 168097: A square mat has a uniform red border on all four sides. The rest of the mat is blue. The width of the blue square is three-fourths the width of the entire square. If the area colored red is 28 m squared, determine the lengths of each side of the mat.
I have tried W^2 - 3/4W^2 = 28
Also W^2 - (W-1/4)^2=28
Mainly need help on setting up. I am alright after the problem is set up into a math problem rather than a word problem.
Thanks

Question 168200: Dear sir/ma'am,
I have a question regarding how to solve Quad. Equations.
My brother has homework, and he has been asked to solve a mixed bunch of quad. equations using either factoring, finding the square roots, or using the quadradic formula.
My question is, how do you know which method to use for each problem? Is there a certain way the equation is set up that indicates what type is most proper?
Thank you!

Question 168648: This particular problem is a more of a quadratic function. I truly wish I could give you some of my calculations but nothing I put together makes sense. I have tried multiplying by the squared denominator, using the square root property but nothing is working! Any help is very much appreciated!!
"Solve each equation for the indicated variable".....
 Solve for R (E > 0)
E squared R is the numerator. (r+R) squared is the denominator.
