Question

F the square below is enlarged by a scale factor of 2.2, what will be the perimeter of the new square?

A square is drawn with a length of 10 units and a width of 10 units

Answer 1

Answer: The perimeter of the original square is the sum of the lengths of all its sides, which are all equal to 10 units:

Perimeter of original square = 4 x 10 = 40 units

When the square is enlarged by a scale factor of 2.2, all of its sides will be multiplied by 2.2:

New side length = 2.2 x 10 = 22 units

The perimeter of the new square is the sum of the lengths of all its sides, which are all equal to 22 units:

Perimeter of new square = 4 x 22 = 88 units

Therefore, the perimeter of the new square is 88 units.
