A verandah is 40m long and 15m broad:
the area is:
A%5Bv%5D=40m%2A15m
A%5Bv%5D=600m%5E2
stones ,each measuring 6dm by 5dm
convert to meters 0.6m by 0.5m
the area of each stone is:
A%5Bs%5D=0.6m%2A0.5m
A%5Bs%5D=0.3m%5E2
to get a number n of stones required, divide:n=A%5Bv%5D%2FA%5Bs%5D
n=600cross%28m%5E2%29%2F0.3cross%28m%5E2%29
n=6000%2F3
n=6000%2F3
n=2000-the number of stones required
