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). How much tarpaulin would be required to make the shelter of height 2.5 m with base dimensions 4 m×3 m?
47 m2
Length of base (l) = 4 m
Breadth (b) = 3 m
Height (h) = 2.5 m
∴ Area of tarpaulin used
=Area of 4-walls+Area of roof
=2h(l+b)+l×b
=2×2.5(4+3)+4×3 m2
=5×7+12=35+12=47 m2
