Answer 2

Answer:

a.) 196.8 square metres / 19,68,000 square centimetres

b.) 0.001702 square metres/ 17.02 square centimetres

Step-by-step explanation:

for a.)

length=20.5 m

breath=960 cm = 9.6 m

Area= length×breath

=20.5×9.6 m

=196.8 square m or 19,86,000 square cm

for b.)

length= 7 dm 3 cm

=0.7 cm + 3 cm

=3.7 cm

breadth= 6 dm 4 cm

=0.6 cm + 4 cm

=4.6 cm

Area= length×breadth

=3.7 × 4.6

=17.02 square cm or 0.001702 square m
