The area of the pentagon is 1,453 squared centimeters.
Given information-
The length of the apothem of a regular pentagon is 20 cm.
The measure of the perimeter of a regular pentagon is 145.3 cm.
The length of the apothem of a rectangular pentagon is 20 cm.
The measure of the perimeter of a rectangular pentagon is 145.3 cm.
<h3>Pentagon-</h3>
Pentagon is the closed shaped polygon which has 5 sides. When these 5 sides are equal in length then the pentagon is called teh regular pentagon. When four of the sides of pentagon make a rectangle then the pentagon is called the rectangular pentagon.
<h3>Area of regular pentagon-</h3>
Area of regular pentagon is half of the product of its apothem and perimeter. It can be given as,
Thus the area of the pentagon is 1,453 squared centimeters.

Answer:
A
Step-by-step explanation:
This shape is a trapezoid. We can divide into two parts: a triangle and a rectangle.
■■■■■■■■■■■■■■■■■■■■■■■■■■
Let A' be the area of the triangle.
● A'= (b*h)/2
b is the base and h is teh heigth.
b= 26-20 = 6 mm
● A'= (6*14)/2 = 42 mm^2
●●●●●●●●●●●●●●●●●●●●●●●●
Let A" be the area of the rectangle.
A"= L*w
L is the length and w is the width.
A"= 14*20
A"= 280 mm^2
■■■■■■■■■■■■■■■■■■■■■■■■■■
Let A be the area of the trapezoid.
A= A'+A"
A= 42+280
A= 322 mm^2
Answer:

The SI unit for density is the kilogram per cubic meter (kg/m3)
Step-by-step explanation:
Answer:
125x³ − 150x²y + 60xy² − 8y³
Step-by-step explanation:
(5x − 2y)³
₃C₀ (5x)³ (-2y)⁰ + ₃C₁ (5x)² (-2y)¹ + ₃C₂ (5x)¹ (-2y)² + ₃C₃ (5x)⁰ (-2y)³
(1) (125x³) (1) + (3) (25x²) (-2y) + (3) (5x) (4y²) + (1) (1) (-8y³)
125x³ − 150x²y + 60xy² − 8y³
