is the perimeter of the triangle whose sides measure 7.5 7.1 and 8.1

22.5 cm

yes it is.

It would be 32.8 centimeters. A square has 4 sides and equal sides. So 8.2 x 4 equals 32.8

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.

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.
