Question

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

Answer 1

Answer:

3 times the perimeter of the first square will that of the new square.

Step-by-step explanation:

Let a square with the side of length 'a' units,

As sides of square are equal,

Perimeter of the square = side + side + side + side

Perimeter of the square = 4 side

Thus,

Perimeter of the square, with original side = 4 x a = 4a units

When side of square is tripled( three times of the original ),

Perimeter of the square = 4 x ( 3 times of a units )

Perimeter of the square = 4 x 3 x a units

Perimeter of the square = 12 a units

Hence,

Perimeter of the square is increased by ( 12 a / 4 a ) or 3 times of the original perimeter.
