Question 1178207: The side lengths of a square are tripled.
a) What is the length’s multiplier? What is the percentage increase of the length?
b) From the new (tripled) length, what percentage decrease would be needed to return to the original length? What is the associated multiplier?

c) What effect does the tripled length have on the square’s Perimeter? It’s Area?

You can put this solution on YOUR website!
let length of square be x
trebled
side = 3x

original perimeter = 4x
Perimeter after trebling = 12x
perimeter is 3 times
Area = x^2
Area after trebling = 9x^2
Area is 9 times
