If you know what the area is for a rectangle you will get this easy. Also if you don't know how to multiply 2 digit numbers then you can't get this. L x W means length x width. Length is 20cm. Width is 15cm. Just multiply both of them and you get the answer.
Gian,
Your problem was really easy. All you have to do is know you can multiply 15by2 then multiply 30by10. It really was easy. Especially if you know how to do it.
P.S.Next time make the numbers harder
