The perimeter is "56 cm". Further explanation is given below.

Step-by-step explanation:

Given:

Area of circle = 154 cm²

As we know,

Area of circle = πr²

On putting the values in the above formula, we get

                154 = \frac{22}{7}×r²

                   r² =  \frac{154*7}{22}

                   r² = 49

                   r² = 7²

⇒         radius, r = 7

Side of square (AB), a = 2r

On putting the value of "r" in the above formula, we get

⇒  a = 2×7

⇒     = 14 cm

Perimeter of square = 4×sides

⇒                                    = 4×14

⇒                                    = 56 cm
