Question

if the side of a squre is tripled, how many times the perimeter of the first square will that of the new squre be?

Answer 1

let the original side of the square be x
perimeter of square=4×side
=4× x =4x ____(i)
according to the question,
new side of square=3x
perimeter=4×3x
=12x

therefore,
the number of times the perimeter of the first square as compared to new square will be

$\frac{12x}{4x}$
=3


the perimeter will be 3 times that of the original square.
