if the area of a rectangle is 1250 units squared, the width is 8x and the length is 12x what is the perimeter
------
Area = L*W = 8x*12x = 1250
Solve for x, then for L and W.
-------------
P = 2W + 2L

+%28+8x+%29%2A%28+12x+%29+=+1250+
+96x%5E2+=+1250+
+x%5E2+=+13.0208+
+x+=+3.6084+

The perimeter is:
+p+=+2%2A%28+8x+%29+%2B+2%2A%28+12x+%29+
+p+=+16x+%2B+24x+
+p+=+40x+
+p+=+40%2A3.6084+
+p+=+144.338+
