Answer:
Dimensions of printed poster are
length is 32 cm
width is 48 cm
Step-by-step explanation:
Let's assume
length of printed poster is x cm
width of printed poster is y cm
now, we can find area of printed poster
so, area of printed poster is
we are given that area as 1536
so, we can set it to 1536
now, we can solve for y
now, we are given
The top and bottom margins of a poster are each 12 cm and the side margins are each 8 cm
so, total area of poster is
now, we can plug back y
now, we have to minimize A
so, we will find derivative
we can use product rule
now, we can simplify it
now, we can set it to 0
and then we can solve for x
Since, x is dimension
and dimension can never be negative
so, we will only consider positive value
now, we can solve for y
so, dimensions of printed poster are
length is 32 cm
width is 48 cm
