Question 519455: The side of a square has length s. The length of a rectangle is 6 cm greater than the side of the square and the width of the rectangle is 3 cm less than the side of the square. The perimeter of the rectangle is 42 cm less than twice the perimeter of the square. Find the dimensions of each figure.

square side = s
rectangle length = s+6
rectangle width =s-3
Perimeter of square = 4s
Twice the perimeter = 8s
perimeter of rectangle = 2*(s+6+s-3)=>2*(2s+3)
=4s+6
4s+6 = 8s-42
4s-8s=-42-6
-4s=-48
/-4
s=12cm side of square
...
length of rectangle = s+6=>18cm
width of rectangle = s-3=>9cm
