Question

Abby is helping her father fence in a part of the yard for a garden. The rectangular area they are fencing in is 4 metres wide and 7 metres long. They need to put a post in the ground every 1.5 metres. How many posts will they need? How many square metres will they have in their garden? How many metres of fencing will they need?

Answer 1

The perimeter of the fence is 2(4+7)=2(11) = 22 metres.

With a post every 1.5, divide 22 by 1.5 = 14.6666...You need at least 15 posts

The area of the garden is 7x4 = 28 square metres.

The fencing needed is the perimeter = 22 meters
