Answer 2

perimeter of a square = 41.6 Units

Area = 108.16 square units

Explanation:

Given:

1. A square paper has  $10\frac{2}{5}$ cm long

To find:

Perimeter and Area

Formula:

Perimeter of a square = 4a

Area of a square = a²

a =   $10\frac{2}{5}$ cm

a is in mixed fraction

a =  $\frac{52}{5}$

Perimeter = 4a

Perimeter = 4($\frac{52}{5}$ )

Perimeter =  $\frac{208}{5}$ Units

perimeter of a square = 41.6 Units

Area = a²

Area =  $(\frac{52}{5})^{2}$

Area = $\frac{2704}{25}$

Area = 108.16 square units
