Question

find the area of a rectangle whose length is 4 2/5 and breadth is 5 4/7 cm fast ​

Answer 1

Answer:

Area of rectangle = l × b

converting mixed fraction to improper fraction

$l \: \: = 4 \frac{2}{5} = \frac{22}{5}$

$b = 5 \frac{4}{7} = \frac{39}{7}$

$\frac{22}{7} \times \frac{39}{6}$

$= \frac{143}{7}$

Am not sure if the answer is right...

Answer 2

Answer:

4 2/5 = 22/5

5 4/7 = 39/7

22/5 x 7 = 154/35

39/7 x 5 = 195/35

195 x 154 = 30030
