Question

Coco buys a very large rectangular chocolate bar and decides that each day, she

will cut the largest possible square off of the bar and eat it. When the remaining
part of the chocolate bar is a square, she will eat all that is left. The table shows
the area, in square centimeters, of the square Coco eats on each day. If Coco
finishes the chocolate bar on Day 6, what was the length of the longer side of the
chocolate bar when Coco bought it?

Table is included need answer ASAP.

Answer 1

Answer: 39

Explanation:

On each of the six days Coco ate a square piece of chocolate with side length 15 cm, 15 cm, 9 cm, respectively. Then find the slope versus. 15*15+9*1=236. Then you have to do 236-200=36. Later 36+3, since there were three numbers to get 39.

Answer 2

On each of the six days Coco ate a square piece of chocolate with side length 15 cm, 15 cm, 9 cm, 6 cm, 3 cm and 3 cm, respectively. Since we know the originally chocolate bar was a rectangle the 6 squares must fit together as shown. The length of the longer side of the original chocolate bar, then, was 15 + 15 + 9 =39 cm
