1tin of paint covers 12m

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)
