A square paper sheet has 10 2/5 cm long side. Find its perimeter and area.

Verified Answer

Length of the side of the square sheet

= 10 2/5 cm

= 52/5 cm

Perimeter = 4 × side

= 4 × 52/5

= 208/5 cm

= 41 3/5 cm

Area = side × side

= 10 2/5 × 10 2/5

= 52/5 × 52/5

= 2704/25 cm²

= 108 4/25 cm²
