Question

1. Find the area of a rectangle whose :(i) length = 15 cm and breadth = 6.4 cm(ii) length = 8.5 m and breadth = 5 m>(ii) length = 3.6 m and breadth = 90 cm(iv) length = 24 cm and breadth = 180 mm​

Answer 1

Answer:

(i)l=15cm,b=6.4cm

Area=(l*b)

=(15*6.4)

=96cm²

(ii)l=8.5m,b=5m

Area=(l*b)

=(8.5*5)

=42.5m2

(iii)l=3.6m,b=90cm

1m=100cm

3.6m=3.6*100

=360cm

Area=(l*b)

=(360*90)

=32400cm²

(IV)l=24cm,b=180mm

1cm=10mm

24cm=24*10

=240mm

Area=(l*b)

=(240*180)

=43200mm²
