Answer
6ft by 15ft
Explanation:
Given the dimension of the poster
Length = 4 feet
Width = 10feet
If the poster is enlarged by a factor of 3/2, to get the new dimensions, you will have to multiply both dimensions by the scale factor as shown:
New length = 4 * 3/2 = 6 feet
New width = 10 * 3/2 = 15feet
Hence the dimensions of the poster after enlargement is 6ft by 15ft
