| Determine the length of the rectangle. Let the length of the rectangle be a, then the width of the rectangle will be a – 10. Make the equation:

(a + a – 10) x 2 = 140;

(2a -10) x 2 = 140;

4a – 20 = 140;

4a = 140 + 20;

4a = 160;

a = 160: 4;

a = 40 m.

Determine the width of the rectangle:

40 – 10 = 30 m.

Answer: the length of the rectangle is 40 meters, the width of the rectangle is 30 meters.
