Answer 2

Length = 10

Width = 13

Explanation:

If the width of a rectangle is 3 units less than the length and if the area is 130 square units, the length is 10 units and the width is 13 units.

Therefore, you have to find what two numbers multiply together in order to recieve 130 units.

A=wl=13·10=130
