Question

A rectangular sheet of paper is 4/7 cm long and 6/9 cm wide. Find it's perimeter .​

Answer 1

Answer:

Given :-

Length of rectangular sheet of paper = 4/7 cm

Breadth = 6/9 cm

Perimeter of rectangle = 2(l+b)

$= 2( \frac{4}{7} + \frac{6}{9} )$

$= 2( \frac{36 + 42}{63} )$

$2 \times \frac{78}{63}$

$= \frac{156}{63}$

$= 2.47 \: cm$

Answer 2

Answer:

52/21

Step-by-step explanation:

perimeter= 2 (l+b)

= 2 (4/7+ 6/9)

= 2(4×9+6×7/63)

=2(36+42)/63)

=2×78/63

=156/63

=52/21
