Question

rectangular sheet of paper is 13/5 cm long and 3/15 cm wide find its perimeter​

Answer 1

Answer:----------

$given \\ rectangle \: sheet \: of \: paper \: \\ length \: = \frac{13}{5} \\ b \: = \frac{3}{15} \\ perimeter \: of \: rectangle \: = 2(l + b) \\ = > 2 \times ( \frac{13}{5} + \frac{3}{15} ) \\ = > 2 \times ( \frac{13 \times 3}{5 \times 3} + \frac{3}{15} ) \\ = > 2 \times ( \frac{39 + 3} {15} ) \\ = > 2 \times ( \frac{42}{15} ) \\ = > \frac{2 \times 42}{15} \\ = > \frac{84}{15} \\ \\ perimeter \: of \: given \: rectangular \: \\ sheet = \frac{84}{15}$

Answer 2

Given :-

rectangular sheet of paper is 13/5 cm long and 3/15 cm wide

To Find :-

We need to find its perimeter

Solution :-

Perimeter of the rectangle = 2 x ( L + B)

Perimeter of the rectangle = 2 x ( 13/5 + 3/15 )

= 84 / 15

Hence , the perimeter of the sheet of paper is 84/15
