Solution

The correct option is B

42 units


To find the Perimeter of square ACEF, we need to know the side.

There are 2 ways to find the side -

Method 1 :

AC = AD2+CD2 = 12+12 = 2 units

Method 2 :

AE = 2 cm and AFE is a right angled isosceles triangle with AF = FE

The sides are in the ratio 1 : 1 : 2

Let AF = FE = x and AE = 2x

2x = 2

x = 2

AF = FE = 2 units

Perimeter of the square = 4 × Side = 4×2 = 42 units
