A boat maker wanted to build a canoe 6 ft long and 2 1/2 wide but decided that those dimensions were too small. The boat maker wants to add 2 ft to both the length and width but also wants to keep the canoe the same shape. Explain why this will not work.
the ratio of length to width would change slightly, before adding on to the dimensions, the ratio is 6 : 2.5 with the added dimensions, the ratio would change to 8 : 4.5 with simple math you can see that 2.5 is less then half of 6 while 4.5 is more then half of 8
Answer:
No, does not form a proportion
Step-by-step explanation:
Consider the provided information.
The length of boat was 6 ft long and 2 1/2 ft wide.
Note: 2 1/2 = 2.5
The dimensions were too small so boat maker wants to add 2 ft to both the length and width but also wants to keep the canoe the same shape.
To be the same shape the ratio should form a proportion if you add 2 ft to both the length and width.
Add 2 in length and width.
New length 6+2= 8
New width 2.5 + 2 = 4.5
Now compare the ratio as shown:
\(\frac{6}{2.5}=\frac{8}{4.5}\\\\ 2.4=1.778\)
Which is not true
Hence, it will not work because it does not form a proportion.
