Question

A rectangular sheet of paper is 3/4 cm long and 2/5 cm wide. then the perimeter is​

Answer 1

Answer:

perimeter=2×(3/4+2/5)

=2×23/20

=23/10cm

Answer 2

Answer:

$p = \frac{23}{10}$

Step-by-step explanation:

Perimeter (P) = 2(L+W)

$p = 2( \frac{3}{4} + \frac{2}{5} )$

$p = 2( \frac{15 + 8}{20} )$

$p = 2( \frac{23}{20} )$

$p = \frac{2 \times 23}{20}$

$p = \frac{23}{10}$
