Percentage change in perimeter is 100%.

Step-by-step explanation:

  • Step 1: Given length of rectangle 1, length = 5 ft and breadth = 3 ft.

Calculate perimeter of R1 = 2 (length + breadth) = 2 (5 + 3)  = 16 ft

  • Step 2: Given dimensions of 2nd rectangle is twice the first, length = 10 ft and breadth = 6 ft.

Calculate perimeter of R2 = 2 (10 + 6) = 32 ft

  • Step 3: Calculate percentage change using the formula, (R2 - R1/R1) [tex]\times[/tex] 100

= (32 - 16/16) [tex]\times[/tex] 100 = 100%
