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 polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the area of a regular decagon with an apothem of 3.8 cm and a side length of 2.5 cm?

The apothem and side length are not consistent. That is, a decagon with an apothem of 3.8 cm cannot have a side length of 2.5 cm.If the apothem is 3.8 cm then area = 46.9 cm2 whileif the side length is 2.5 cm then area = 48.1 cm2.The two answers agree at the tens place and so the most accurate answer is 50 cm2 to the nearest 10.
