What this lesson teaches

Solve length problems by adding lengths together or subtracting to find a difference. Keep the same unit.

Worked examples

Example 1

A path is 34 meters. You walk 20 meters. How much is left? 34 - 20 = 14 meters left.

Example 2

A fence is 26 feet and you add 15 more feet. Together that is 26 + 15 = 41 feet.

Example 3

A rope is 50 cm. You cut off 18 cm. What is left? 50 − 18 = 32 cm.

Practice questions

  1. A fence is 25 feet, then you add 18 more feet. How long is the fence now?
  2. A ribbon is 40 cm. You cut off 15 cm. How much is left?
  3. One rope is 22 inches and another is 13 inches. How long are they together?
