Answer 2

The cost of making painting is Rs. 750

Step-by-step explanation:

as the figure is not shown here ,

assuming that the dimensions of the canvas is 60 cm by 40 cm

then area of the canvas = length × breadth

= 60×40

= 2400 cm²

if  A border of width 15 cm is to be left blank in the boundary of the painting

then length of the painting area = 60 -(15+15) = 60 - 30 = 30 cm

breadth of of the painting area = 40 -(15+15) = 40 - 30 = 10 cm

then

area of the painting area = length × breadth = 30 ×10 = 300 cm²

cost of painting per cm² = Rs. 2.50

then cost of painting 300 cm² = 300× 2.50 = Rs. 750

hence ,

the cost of making painting is Rs. 750
