Answer:
1453 cm²
Step-by-step explanation:
The area of a regular polygon is given in terms of its perimeter and apothem by ...
A = (1/2)Pa
A = (1/2)(145.3 cm)(20 cm) = 1453 cm²
The area of the pentagon is 1453 square centimeters.
Answer:
Identity property of multiplication (multiplying a number by one will result in that number)
Step-by-step explanation:
Answer:
Length of segment
units = 8.94 units
Step-by-step explanation:
Given:
End point of line: (2,1)
Midpoint of line: (-2,-1)
To find length of line segment.
Solution:
Distance from endpoint to midpoint is half the length of segment as the midpoint divides the line into equal halves.
Distance from end point to mid point can be found out using distance formula:

Plugging in points for end point (2,1) and midpoint(-2,-1).





Length of half segment
units
∴ Length of segment =
units
