Which of the following geometric figures possesses a greater perimeter than the remainder?
Show answer Hide answer
Answer: C. A rectangle with 10 cm as length and 40 sq.cm as area
Explanation
The perimeter of the specified rectangle is calculated as two times the sum of length and width. The area is forty square centimeters and the length is ten centimeters, making the width four centimeters. Adding length and width gives fourteen centimeters, and multiplying by two yields a total perimeter of twenty-eight centimeters. A square with an area of thirty-six has side lengths of six and a perimeter of twenty-four. An equilateral triangle with nine centimeter sides has a total perimeter of twenty-seven centimeters. A circle with a radius of four centimeters has a circumference of approximately twenty-five point one centimeters.
The square yields a smaller perimeter of twenty-four centimeters compared to the twenty-eight centimeter rectangle. The equilateral triangle produces a perimeter of twenty-seven centimeters which remains smaller than the rectangle. The circle results in a circumference of roughly twenty-five point one centimeters, which is also smaller.
