Answer:
The perimeter and the diagonal of the square are 32 cm and 16 cm respectively.
Step-by-step explanation:
Given, Area of the square = 64 cm²
Side = Square root of 64 = 8
Hence, Perimeter = 4 × side
= 4 × 8 = 32 cm (ans).
Area of square = 1/2 × d²
=> 64 = 1/2 × d²
=> d²/2 = 64 => d²/2 = 8²
=> d/2 = 8 => d = 16 cm (ans).
