Answer:
308cm²
Step-by-step explanation:
Assuming the given unit is in cm
The expression for the area of a regular Octagon is
A=2(1+√2)a²
Given the apothem a = 8cm
Substituting we have
A=2(1+√2)8²
A= 2(1+1.414)64
A= 2(2.414)64
A= 308cm²
Multiply both sides by -3 to get rid of the negative and the fraction.
X - 3 = 21
Move the constants over to isolate the variable
X = 24
