Question

A rectangular field is 13/2 m long and 14/5 m wide. Find the perimeter of the field.​

Answer 1

Answer:

Given - Length is 15 2/3

- breath is 12 4/5

=>perimeter of a rectangle = 2x( l + b )

=> 2x( 15 2/3 + 12 4/5 )

Therefore convert mixed fraction into improper fractions.

=> 15 2/3 = 47/3

=> 12 4/5 = 64/5

\begin{gathered} = > 2x( \frac{47}{3} + \frac{64}{5} ) \\ \end{gathered}

=>2x(

3

47

+

5

64

)

For adding the fraction :

find LCM of denominator (3 and 5)

LCM is 15

\begin{gathered} = > 2x \frac{(47 \times 5}{(3 \times 5} + \frac{64 \times 3)}{5 \times 3)} = \frac{235 + 192}{15} \\ \\ = > 2x \frac{427}{15} \end{gathered}

=>2x

(3×5

(47×5

+

5×3)

64×3)

=

15

235+192

=>2x

15

427

Therefore, the perimeter of rectangle is 427/15 .
