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
