s and d are related by s² + s² = d² and the diagonal is 10 units long
Step-by-step explanation:
- Step 1: Find relation of s and d.
Relation is given by this equation s² + s² = d²
- Step 2: Given side of the square is 7 units, find the diagonal, d.
d² = 7² + 7² = 49 + 49 = 98
∴ d = √98 = 9.89 ≈ 10 units
