mrs.ellsworth wants to put up a fence around her square garden. the garden has an area of 25 square feet . how much fencing material is needed to fence in the garden

Answer 1

Hi,

To find the fencing material means to calculate the length around the square garden, or the perimeter of the square shaped garden.

 

Area , A, is given as 25 sq, ft.

Formula for Area of a square, A = s²

25 = s²

This can be written as   

s²  = 25

Take the square root of both sides, √(s²) = √(25)

 

                                                       s = 5 ft

 

The perimeter of a square can be calculated, P = 4(s), because all the four sides are equal

 

P = 4(5) = 20 ft

 

She needs 20 ft of fencing materials.

I think this will help you.
