Question

The area of the octagon below is 10,391. 9 square millimeters. An octagon has an apothem of 56 millimeters and an area of 10,391. 90 square millimeters. What is the approximate perimeter of the octagon? Round to the nearest whole number. Mm What is the approximate length of one side of the octagon? Round to the nearest whole number. Mm.

Answer 1

The perimeter of the octogon is 371.14 millimeters, and each side is about 46.4 millimeters.

Given that an octagon has an apothem of 56 millimeters and an area of 10,391.90 square millimeters, to determine what is the approximate perimeter of the octagon and what is the approximate length of one side of the octagon, the following calculation must be performed:

• (Perimeter x apothem) / 2 = Area
• 56X / 2 = 10,391.90
• 56X = 10,391.90 x 2
• X = 20,783.80 / 56
• X = 371,139
• 371.14 / 8 = 46.4

Therefore, the perimeter of the octagon is 371.14 millimeters, and each side is about 46.4 millimeters.
