mang pedring want to build square table

the length is 30cm. longer than its height....
how would you represent the height of the table?

H = L - 30

To represent the height of the table, we can define a variable. Let's call the height of the table "h".

Based on the given information, we know that the length of the table is 30cm longer than its height. So, we can represent the length of the table as "h + 30".

Therefore, the height of the table can be represented as "h", and the length can be represented as "h + 30".
