You subtract 5 from 9 to get 4; 5(9)= 45 9(4)=36 45+39=81
Length of PS= 3.99 units
Length of QS=2.08 units
Area of triangle PQR=14.12units²
12 inches = 1foot

6yards = 18feet
Rerange the question:
If edging cost $2.32 per 1foot stone, and you want a double layer of edging around your flower bed that is 18feet by 3feet. How much will edging you flower bed cost?
Perimter:
2(18+3)=42
And since you want to double it; double the perimeter too.
42(2)=84
2.32(84)=194.88
