Question

amelia is building 3 square garden beds that are all the same size. she arranges them side by side to separate certain plants. amelia wants to know the total area of the beds.
s = length (ft) of one side of a garden bed
write an expression to represent the total area of all 3 garden beds.

Explanation:

Step1: Find area of one square bed

A square's area is side squared. So, area of one bed is $s^2$ (since side length is $s$).

Step2: Find total area for 3 beds

Multiply the area of one bed by 3. So total area = $3\times s^2 = 3s^2$.

Answer:

$3s^2$
