You are redecorating your room and you only have one wall left to paint. The length of the wall is 13.25 feet and the width of the wall is 9 ft. If the hardware store needs to know the area of the wall to determine how much paint you still need, what is the area that you will report to them?

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

Yea they are simplyfiy the ratios
