Answer:
17 tins
Step-by-step explanation:
Split the figure into two:
The top rectangle and the bottom rectangle
Now find area of the top one.
=> A = lb
=> 17 x 9.7
=> 164.9 m²
Now the bottom one.
=> A = lb
=> A = 15.9 x 2.3
=> A = 36.57 m²
So, total area is :-
= 164.9 + 36.57
= 201.47 m²
No. of tins = 201.47/12
= 16.78
= 17 tins (to cover remaining area)
