Two corresponding sides of two similar pentagons are 12 cm and 28 cm. what is the ratio of the areas of the pentagon? a. 27/343 b. 28/12 c. 12/28 d. 9/49

The area of a pentagon is found through the following formula:



s is equal to the side length.

Plug 12 and 28 into the formula.

A(12) = 247.75
A(28) = 1348.85

Divide the first result by the second result.

 ≈ 

9/49 is equal to this decimal.

The answer is 9/49.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
