Question

carpet is 30 metre 75 cm long and 80 cm wide find its cost at rupees 150 per square metre

Answer 1

total cost
first find area
we prefer in metre bcoz the rate is also in metre
so,
30.75* .80 m
=24.6m²
now cost =24.6*150
3690
so the total cost is 3690
hope it helps you

Answer 2

area of the carpet=3075cm×80 cm
area of the carpet=246000cm square
cost =150m square
we have to change the area in m square
1m square=10000cm square
150m square=150×10000cm square
150m square=1500000cm square
cost =1500000×246000
cost =369000000000
