<PRE><B>Question 970280</B>
The area of a rectangle is 1260. Find the dimensions of the rectangle if we know that the length is 48 longer than 3 times the width. Use the quadratic formula in order to solve.
-----------
Area = L*W = 1260
(3W+48)*W = 1260
(W + 16)*W = 420
W^2 + 16W - 420 = 0
*[invoke solve_quadratic_equation 1,16,-420]
===============
W = 14
L = 90
