A=1/2aP
a=19, P=70 (7*10)
A=1/2(19)(70)
A=1/2(1330)
A=665 cm ^2

What is the area of a decagon with the Apothem Y and the side length X?
5xy
A regular octagon with sides of length 7 and an apothem of length 10.49 has an area of?
Area in square units = 0.5*(apothem)*(perimeter)
Is a decagon a regular figure?
Any polygon is regular if its sides are all the same length, or irregular if they're not. If all 10 sides of your decagon are the same length, then you have a regular decagon. If they're not, then you have an irregular one.
How do you form up a 24 ft decagon?
With the information given it is not possible. Does 24 ft refer to a length of a side, the longest side, the shortest side, a diagonal, an apothem? Knowing the answer to that question can only help if the decagon is regular - and on the basis of the question, there is no reason to assume regularity.
What is the formula of the perimeter of a regular decagon?
10*length of a side.
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.
What is the area of a regular decagon with a side length of 7 cm and an apothem of 10.8 cm?
378 cm ^2

What is the area of a regular decagon whose side is 1.2 and whose apothem is 1.85?
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.
What is the area of a regular nonagon with a side length of 9 and an apothem of 16?
A regular nonagon with a side length of 9 has an apothem of 12.4 not 16. So the question is inconsistent.
A regular octagon with sides of length 7 and an apothem of length 10.49 has an area of?
Area in square units = 0.5*(apothem)*(perimeter)
Is a decagon a regular figure?

What is the apothem of a regular hexagon?
If the hexagon has side length s, then the apothem is sqrt(3) * s / 2.

A regular octagon with sides of length 8 and the apothem of length 9.66 has an area of what?
309.12
What is the formula for finding the area of a regular polygon with perimeter P and apothem length a?
A = (1/2)Pa A being the area, P being the perimeter of the regular polygon, and the apothem length being a.
A regular octagon with sides of length 7 and an apothem of length 8.45 has an area of what?
The area of a regular octagon: A = (2 x apothem)2- (length of side)2 or in this case A= (2 x 8.45)2 - 72
