Answer:
The perimeter will be 10 times the original.
Explanation:
Formula for Perimeter of rectangle is
2l + 2 w. From the diagram shown, the perimeter is 2×6 +2×3 = 12+6 =18cm
If if each side is increased by a factor of 10
Our length becomes 6×10= 60cm
Our width becomes 3×10= 30cm
New perimeter becomes
2×60 + 2×30
= 120+60 = 180cm
New perimeter(180 cm)= 10× original perimeter (18cm)
So The perimeter will be 10 times the original.
