387.5 centimeters (10 sides each the same length)
is the perimeter of the triangle whose sides measure 7.5 7.1 and 8.1
22.5 cm
yes it is.
A square has sides of length 8.2 centimeters. What is the perimeter?
5x + 20
312cm
Area of a regular polygon equals to the one half of the product of its perimeter with the apothem. So we have: A = (1/2)(a)(P) Since our polygon has 10 sides each with length 1.2, the perimeter is 12 910 x 1.2). Substitute 12 for the perimeter, and 1.85 for the apothem in the area formula: A = (1/2)(a)(P) A = (1/2)(1.85)(12) A = 11.1 Thus, the area of the decagon is 11.1.
5 x 8.9...
A pentagon has five sides- 5 * 12.5 = 62.5
A regular hexagon has 6 sides of equal length ("hex" means six). The perimeter is just the length of all the sides added up. So, Perimeter = 6 x 7 = 42 cm
Unless I've really misunderstood, the perimeter of a hexagon whose sides are length 4.55 is 6*4.55 = 27.3. As a hexagon has 6 sides.
is the perimeter of the triangle whose sides measure 7.5 7.1 and 8.1
A decagon.
