Dear Student, Diagonal of a square = (side)215 = (side)2side = 152 = 1522 ×2 = 1522 mPerimeter = 4×side =4×1522 = 302 m Regards,

Please solve this

Dear Student,

D i a g o n a l o f a s q u a r e = (s i d e) \sqrt{2} 15 = (s i d e) \sqrt{2} s i d e = \frac{15}{\sqrt{2}} = \frac{15 \sqrt{2}}{\sqrt{2} \times \sqrt{2}} = \frac{15 \sqrt{2}}{2} m P e r i m e t e r = 4 \times s i d e = 4 \times \frac{15 \sqrt{2}}{2} = 30 \sqrt{2} m
