Question

b. 14.2 cm 14.2 cm p = a =

Explanation:

Step1: Calculate the perimeter

The formula for the perimeter \(P\) of a square is \(P = 4s\), where \(s\) is the side - length. Given \(s=14.2\) cm.
\(P = 4\times14.2\)

Step2: Calculate the area

The formula for the area \(A\) of a square is \(A=s^{2}\).
\(A=(14.2)^{2}=14.2\times14.2\)

Answer:

\(P = 56.8\) cm, \(A = 201.64\) cm²
