Question

A tile is 30 m 75 cm long and 60 cm wide. Find its cost at Rs. 23 per square meter

Answer 1

Answer:

Step-by-step explanation:

First we will have to convert breadth and height into m

So 75/100= 0.75m

And 60/100=0.6m

Total Surface area= 2(lb+bh+hl)= 2( 30×0.75+0.75×0.6+30×0.6)= 2(22.5+ 0.45 + 18)

= 45.0 + 0.9+ 36

= 81.9 m2

= Cost = 81.9 × 23

= 1883.7 rupees
