Answer:

2x−3y

Step-by-step explanation:

Let us factorize the given expression of area,

Let us factorize the given expression of area,8x2+18xy−45y2=8x2−12xy+30xy−45y2=4x(2x−3y)+15y(2x−3y)=(4x+15)(2x−3y)

Let us factorize the given expression of area,8x2+18xy−45y2=8x2−12xy+30xy−45y2=4x(2x−3y)+15y(2x−3y)=(4x+15)(2x−3y)It is given that the expression for one side is 4x+15y hence the expression for the length of the other side will be, 2x−3y.
