Question

If the area of a square reduces by 51%, the percentage reduction in its perimeter will be:

Answer 1

Change in area is 76%

Answer 2

Answer:

Approximately 25.5%

Step-by-step explanation:

Visualizing a square that has a side length of 100, now imagine the same square but now reduced into a rectangle, the rectangle has a breadth of 49 and length of 100. Now find the perimeter of both shapes: the square will have a perimeter of 400 and the second one have 298 as its perimeter. Now: 400-298 = 102 and 102/400 = 0.255 and 0.255 x 100 = 25.5 which is the our answer
