A rectangle garden is paved with 1m square paving stones. the garden is 15m long and 10m wide how many paving stones are used?

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

First you need to find the area of the garden.

a=lw

a = (15) (10)

a=150 meters

150/1=150

you need 150 paving stones.
