Question

a carpet is 30 m 75 cm long and 80 cm wide. find its cost at Rs. 150 per square meters​

Answer 1

given,
length of carpet = 30m 75cm = (30×100)+75 = 3075cm
Width of carpet = 80cm
area = length X breadth
=> 3075×80
=> 246000 sq. cm
1 sq.m = 10,000 sq.cm
246000 sq.cm = 246000/10000 sq.m
=> 24.6 sq.m
Cost of 24.6 sq.m carpet = (24.6 × 150) = 3690
hence the required cost is 3690 Rs .

Answer 2

Length of carpet = 30m75cm

= 3075 cm

Breadth = 80 cm

Area of carpet = (80×3075) cm²

=> 246000 cm²

1m² = 10000cm²

=> 246000/1000

=> 24.6 m²

Cost of carpet = (150×24.6) = 3690
