Answer:
1) area = l×b
= 46×25 cm²
= 1150 cm²
2) area = l×b
= 9× 6 m
= 56 m²
3) area = l×b
= 14.5×6.8m²
= 9860 m²
4) area = l×b
= 205×60 cm²
= 12300 cm ²
= 123 m²
5) area = l×b
= 3.5×2 km²
=7.0 km²
= 7 km²
that's your answer
hope this will help you dear
mark as brainiest answer
give me thanks
Answer:
i) length = 46cm , breadth = 25cm
Area = l × b
= 46 × 25
= 1150cm²
____________________
ii) length = 9m , breadth = 6m
Area = l × b
= 9 × 6
= 54m²
____________________
iii) length = 14.5m , breadth = 6.8m
Area = l × b
= 14.5 × 6.8
= 98.6m²
____________________
iv) length = 2m 5cm , breadth = 60cm
length = (2×100) + 5 cm
= 205cm
Area = l × b
= 205 × 60
= 12300cm²
____________________
v) length = 3.5km , breadth = 2km
Area = l × b
= 3.5 × 2
= 7km²
