Suzanne has a rectangular garden which is 18 feet long and 11 feet wide. she has 168 square foot of paving stones, and she wants to build a pathway around the border of the garden. how wide will the pathway be?

width = 2.5 feet

Step-by-step explanation:

Suzanne has a rectangular garden which is 18 feet long and 11 feet wide.

Area of the garden = length times width = 18 times 11= 198 square foot

Let 'w' be the width of the border

Length of the garden with border = 18+2w

Width of the garden with border = 11+2w

Area of the garden with border =

Area of the border =

She has 168 square foot of paving stones,

Solve for w

apply quadratic formula

a= 4, b= 58 and c=-168

we get two values for w

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
