The area of a rectangle or field is 1710 ft.² the length of the field is 45 feet what is the width of the field

1710/45 will give you the width (38) because length times width equals the area.

Hello!

The formula for area is l * w.

45 * ___ = 1,710 sq ft

The opposite of multiplication is division, so that means you must divide the area (1,710) by the length (45) to find the width:

1,710 : 45 = 38

Therefore, the width of the field is 38 ft.
