first you need to find the area of the garden.
a=lw
a=(15)(10)
a=150 meters

150/1=150

so first you need to know how much area the garden is

so areia=legnth times width

area=15 times 10
area =150 m^2 (square meters)

each stone is 1 by 1 so area of each stone is 1 m^2

150/1=150
you need 150 paving stones
