Step-by-step explanation:
Advertisement figure is in the shape of a rectangle.
To find the total cost, first we need to know the total area.
Length of advertisement = 25 cm
Bredth of advertisement = 20 cm
Area of advertisement = length x Bredth
= 25 x 20
= 500 cm^2
If cost of 1 cm^2 = Rs. 20
Cost of 500 cm^2 = 500 x 20
= 10000
So, Total cost is Rs. 10000
I hope it will help you.
