Surface area is square units, so you would need to square the scale factor.
The length was tripled, which means it is a scale factor of 3
3^2 = 9
The surface area would increase by a factor of 9.
The answer is B.
Answer: 22 2/3 feet
Step-by-step explanation:
From the question, a concrete company pours 8 sections of sidewalk each of which is 2 5/6 feet long. The length of the entire sidewalk that the concrete company pours will be calculated by multiplying 8 by 2 5/6 feet. This will be:
= 8 × 2 5/6
= 8 × 17/6
= 136/6
= 22 2/3 feet
I'm gonna need some sort of diagram...
A figure that has no endpoints is called a line.
Hope this helps you with your homework~!
