If the side of a square is tripled, how many times the perimeter of the first square will that of the new square be? |
|
Answer» Let the length of the square be a. Perimeter of square = 4 x side = 4 x a = 4a Side of new square = 3 x a = 3a Perimeter of new square = 4 x side = 4 x 3a = 3 x 4a = 3x perimeter of original square. ∴ The perimeter of new square will be three times the perimeter of original square. |
