Question

A carpet is 30 m 75 cm long and 80 cm wide. Find its cost at Rs. 150 per square meter

Answer 1

HEY THERE!

Length of the carpet, l =30m 75cm = 30×100cm = 3075cm

Breadth of the carpet, b = 80cm

Area of the carpet = Length × Breadth

                             = 3075 × 80

                             = 246000 cm²

Now,
Area in metres = 246000/100

                         = 2460m²

Cost per m² = 2460 × 150
 
                    = Rs. 369000

HOPE IT HELPED ^_^

Answer 2

Hey!

Length(l) = 30 m + 75 cm = 3075 cm
Breadth(b) = 80 cm

It's making a rectangle!
So, 
Area = l x b
         = 3075 x 80 
         = 246000 cm^2 or 2460 m^2
Cost at Rs. 150 = 150 x 2460
                          = Rs. 369000 (Ans)
