Question

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?

Answer 1

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.
