David is building a rectangular fence around his garden. The short side is 15 meters and the long side is double that amount. What is the perimeter of
the garden fence?

Respuesta :

Solution:

Note that:

  • Side₁ (Short side) = 15 meters
  • Side₂ (Longer side) = 2(15) = 30 meters
  • Perimeter = 2L + 2B

Substituting the values into the expression:

  • 2L + 2B
  • => 2(15) + 2(30)
  • => 30 + 60
  • => 90 m

The perimeter of the garden fence is 90 meters.
