Question

11) The length of a rectangular field is 45 m and 35 m wide
What is the perimeter of a rectangular field?
12) Rani had Rs.25.50 with her, she bought a book for
Rs.16.75. Find the amount left with her.
13) Write 4 equivalent fractions of 7​

Answer 1

Answer:

11)

Length = 45m

Breadth= 35m

$\color{black}\boxed{\colorbox{saffron}{Perimeter-2( length+breadth)}}$

= 2(45+35)

= 2×80

= 160 m

‎ ‎

‎ ‎

‎ ‎

12)

Amount left with Rani = 25.50-16.75 = Rs 8.75

‎ ‎

13)

$\frac{4}{7} = \frac{4}{7} \times \frac{2}{2} = \frac{8}{14}$

Hence, $\frac{8}{14}$ are equivalent to $\frac{4}{7}$

Answer 2

Answer:

11)

Length = 45m

Breadth= 35m

$\color{black}\boxed{\colorbox{saffron}{Perimeter-2( length+breadth)}}$

= 2(45+35)

= 2×80

= 160 m

12)

Amount left with Rani = 25.50-16.75 = Rs 8.75

13)

$\frac{4}{7} = \frac{4}{7} \times \frac{2}{2} = \frac{8}{14}$

Hence, $\frac{8}{14}$ are equivalent to $\frac{4}{7}$
