(1) length = 46 cm and breadth = 25 cm
(ii) length = 9 m and breadth = 6 m
(iii) length = 14.5 m and breadth = 6.8 m
(iv) length = 2 m 5 cm and breadth = 60 cm
(v) length = 3.5 km and breadth = 2 km
$\pi \times 23$
​

Answer 1

Answer:

1)46×25=1150m

2)9×6=54m

3)14.5×6.8=98.6m

4)2.5×60=150m

5)3.5×2=7km

Step-by-step explanation:

Area of rectangle =length ×breath

may be it is a correct answer

Answer 2

Step-by-step explanation:

1) area = length × breadth

46 × 25

1150 cm

2) area = length × breadth

9×6

54 m

3) area = length × breadth

14.5 × 6.5

94.25 m

4) area = length × breadth

205 × 60

12300 cm and 123 m ( 1 m = 100 cm ; 2m = 200 cm = 200 + 5 = 205 cm)

5) area = length × breadth

3.5×2

7 km
