Answer 2

         

Let the length be x meters.

So the width becomes 4x/5 meters.

Perimeter = 80 m

⇒ 2(x + 4x/5) = 80 m

⇒ x + 4x/5 = 80/2 m

⇒ (5x + 4x)/5 = 40 m

⇒ 9x/5 = 40 m

⇒ x = 40 × 5/9  m

⇒ x = 800/9  m

⇒ x = 88 and 8/9 meters

⇒ x ≈ 88.89 meters

So the length is approximately 88.89 meters, or we can say 89 meters.

Let's find the width.

4x / 5

⇒ 4 × (800 / 9) / 5

⇒ 3200 / 9 / 5

⇒ 71 and 1/9 meters

⇒ 71.11 meters (approx.)

So the width is approximately 71.11 meters, or we can say 71 meters.
