Question

A RECTANGULAR SHEET OF PAPER IS 3 2/5 cm long and 4 1/5cm wide. Find its
perimeter?​

Answer 1

Answer:15 1/5 or 76/5

Step-by-step explanation:

Length = 17/5

Breadth = 21/5

Perimeter = 2(length + breadth)

Perimeter = 2(17/5+21/5)

Perimeter = 2(38/5)

Perimeter = 76/5

Perimeter = 15 1/5

Answer 2

Answer:

$Perimeter (P) = 15.2\:cm$

Step-by-step explanation:

Dimensions of a rectangular sheet:

$Length (l) = 3\frac{2}{5}\:cm$

$Breadth (b) = 4\frac{1}{5}\:cm$

$Perimeter (P) = 2(l+b)\\=2(3\frac{2}{5}\:cm+4\frac{1}{5}\:cm)$

$=2(\frac{17}{5}+\frac{21}{5})\\=2(\frac{17+21}{5})\\=2\times \frac{38}{5}\\=\frac{76}{5}=15.2\:cm$

Therefore,

$Perimeter (P) = 15.2\:cm$
