Question

The dimensions of a rectangular photograph are odd consecutive integers. The area of the photograph is
255
square inches. Find the lengths of each side.

 

please help me solve this

 

Answer 1

15 and 17

15 x 17 = 255

To end in a 5 for area means one side must end in a 5

15x15=225, so you need slightly more. They have to be odd

so 15 x 17 are the dimensions.
