Kate wants to build a fence around her garden to prevent her rabbits from eating her vegetables. The rabbit fencing costs $7.50 per metre. How much will it cost to enclose a square garden with an area of 144m^?

It will cost $360 to enclose a square garden.

We need to find the perimeter of the square to know the number of meter needed and multiply it to the unit cost of the fence to get the total cost.

Given:

fence = 7.50 per meter

Area of a square = 144 m²

Area of a square = s²

s = √144m²

s = 12m

Perimeter of a square = 12m x 4 sides = 48 meters.

48 meters x $7.50 = $360
