U1 Summative Review

The length of Ace's garden will be 12 more than 3 times its width.

The length of Addi's garden will be 8 less than 2 times its width.

The widths of the two gardens will be the same.

Write an expression for each garden to represent the amount of chain link fencing Ace and Addi will need to fence in their gardens. (you should input 2 different expressions)

The length of Ace's garden will be 12 more than 3 times its width.

The length of Addi's garden will be 8 less than 2 times its width.

The widths of the two gardens will be the same.

If the amount of chain link fencing enclosing each garden is equal, what would the dimensions of each garden need to be?
