Ravish wanted to make a temporary shelter for his car by making a box-like structure with tarpaulin that covers all the four sides and the top of the car (with the front face as a flap which can be rolled up). Assuming that the stitching margins are very small, and therefore negligible, how much tarpaulin would be required to make the shelter of height `2. 5 m` with base dimensions `4mx3m ?`

Explanation

Area of tarpaulin used=Area of `4` walls+Area of roof
`'2h(l+b)+l×b=2×2.5(4+3)+4×3 m^2=47m^2`'
