8cm2.
~35.36 cm
Use Pythagoras: Diagonal² = √(2 × sidelength²) → diagonal = side_length × √2 → diagonal = 10 cm × √2 ≈ 14.1 cm
16 cm squared.
It is: 0.5*4*4 = 8 square cm
The square's diagonal is 11.314 cm
The area is 72 cm2

Check
14.142 cm (rounded)
32 cm² = 8cm²/2
Use Pythagoras: diagonal² = length² + width² → diagonal² = (10 cm)² + (15 cm)² → diagonal = √(10² + 15²) cm = √325 cm = 5 √13 cm ≈ 18 cm
Side of square = 10 cm, Area = Side2 = 102 cm2
