Our vegetable patch has a very old hose, with a lot of holes. We decide we have to change it.
We need to calculate...
How many metres of hose do we need for one patch?
270cm x 4
25cm x 2
___________
1130cm
Then we calculate for the 4 patches, so...
1130cm x 4= 4520 cm
That's the same as 45m and 20cm.
Let's change it!!
We need new hose, rings, measuring tape, pliers and scissors.
