Question

find the perimeter of a square whose area is 25 sq cm

Answer 1

The answer is 20cm....

Answer 2

area of a square = a² = 25 cm²
                            => a = √25 cm
                            => a = 5 cm
Now, 
Perimeter of a square = 4a
                                    = 4 (5) cm
                                    = 20 cm
