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.
So, your problem is ((3x+2))/4) = ((8x-1)/5)?
If so, X= 14/17
If 2 1/2 centimeters make 1 inch, do 12 x 2 1/2, you should get 30 centimeters
